The main goal of this research is to provide an approach on the possibility of using vertical-axis turbines to harness the periodical tidal current and the hydrokinetic flow from ships and vessels, which run continuously in the Suez Canal waterway, for a desalination process. The turbine rotor type and the design parameters have been selected carefully looking for self-starting and best performance under low flow velocities with independency of the flow direction. Experimentally, the model has been fabricated using additive manufacturing process, and tested in a water flume under different upstream flow velocities. Power curves have been obtained for each operating condition. Additionally, the non-dimensional tip speed ratio and power co-efficient curve have been characterized. Numerically, an intensive three-dimensional simulation has been carried out in order to obtain a better understanding of the complex hydrodynamic flow phenomena around the turbine rotor.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122548332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their reliability and efficiency play an integral part in ensuring the commercialization of particle-based CSP technology. Heat loss/leakage from TES walls, particle erosion, thermal and structural stresses during charging/discharging, and hot/cold startup are some of the roadblocks that need to be addressed adequately before commercializing the PHR-CSP technology. To achieve this target, our teams at King Saud University (KSU) and Georgia Institute of Technology (GIT) have successfully demonstrated the multilayered TES bin in the past to store solid particles at a temperature of 700°C. To achieve a higher thermal efficiency of the plant, the particles are required to be heated at temperatures above 1000°C. This causes high thermal and structural stresses to the TES bin walls or layers. At such high particle temperatures, it is important to understand the material properties and interactions between different layers of the TES bin because each layer has different thermal conductivity and coefficient of linear thermal expansion. In this paper, the results of thermal and structural analysis on the TES bin design will be presented and interpreted as how the TES wall layers (insulating firebrick, insulating perlite concrete, expansion layer, and reinforced concrete) will interact with each other. This analysis is important to understand that how thermal and mechanical stresses affect, not only the materials but their interfaces as well. Moreover, it will provide an initial assessment of the TES bin’s thermal and structural integrity at high temperatures.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130239622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this work is to explore the enhancement of the lift and reduction of the drag for energy harvesting purposes. One way of achieving this goal is by controlling the separation of the incompressible laminar boundary layer through blowing and suction. However, in this work it is passively controlled by the cylinder slit. Different slit orientation (azimuth angles: 0, π/12, π/6, π/4, 5π/12, and π/2) at 10% slit-to-diameter ratio was considered. The work was carried out numerically by seeking solution to the unsteady Navier-Stokes equations. Validation was done experimentally utilizing the 2D vertical soap film tunnel available in our laboratory at Khalifa University. The visualization in soap film tunnel exploits the optical properties of soap film and relies on the wake formation patterns and the frequency at which vortices shed using well developed imaging techniques. These flow visualizations of the vortex shedding behind the cylinder with and without slit were recorded and analyzed to infer its Strouhal number (St = f.D/U). From the common Roshko’s graph (Re vs St) the Reynolds number was determined, and the film property was evaluated. Using common flow as baseline the technique can be used to validate numerous 2D-flow simulations, airfoils, bluff bodies, and even the oscillating flow around them. The details of the soap-film technique and parameters for successful experimentation are provided and demonstrated on slitted cylinder. The results are validated using numerical technique and the results from the literature.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130721391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TAEs are a promising technology since they are environmentally friendly and require low maintenance and costs. The main component of the TAE device is the stack which is a solid porous material that allows heat transfer between the fluid and stack plates. Thermoacoustic engines take heat from a hot reservoir and converts some of the heat energy inside the stack to sound energy while dumping the excess to the heat sink. The purpose of this paper is to investigate the stack length and position using the experimental apparatus as well as the numerical modelling. Experimentations are conducted alongside the numerical analysis. The numerical model is governed by the non-isothermal conjugated heat flow of the unsteady Navier-stokes equations. Pressure and velocity are monitored at different locations along the resonator. Experiments conducted showed that the stack position and length have an influence on the efficiency of the TAE. For both lengths tested, the efficiency increased as the center position of the stack moved further away from the pressure anti-node, however this was not observed in the numerical analysis, as the maximum output was obtained with stack placed at 0.3L from the closed end of the tube. Moreover, the longer stack of 9cm gave a better performance than the shorter stack of 4.5cm.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124566431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important consideration for increasing PV panel energy production is to carefully select the tilt angle relative to the ground of the installed panel. Tracking arrays resolve this issue by dynamically tracking the sun throughout the course of the day, but tracking technology includes additional capital costs and is not affordable for residential systems. The goals of this study are to explore the use of a bi-annual fixed tilt array, where the tilt angle of the fixed array is changed at two times in the year to better capture the seasonal variation in solar irradiation. The goal of this study is to use optimization techniques to resolve the ideal tilt angles as well as the optimal time to change between these two angles for every state in the continental United States. Biannual arrays are then compared to fixed tilt and 1D tracking arrays while examining local weather variations and their effect on the optimal PV tilt angle and solar PV production. In general, PV panels with a fixed tilt in states at higher latitudes collect 90% of the energy that a 1D tracking array would collect, whereas bi-annual tilt angle array produce on average 97% of the energy that a 1D tracking array collects, making the bi-annual tilt method nearly as effective as 1D tracking at these latitudes. Fixed tilt arrays in the southern United States collect on average 85% of the energy that a 1D tracking array would collect, whereas bi-annual tilt arrays in the southern United States produce at maximum 90% of the energy that a 1D tracking array produces. Nearly all states optimize energy production when the tilt angle is changed during the month of March and the month of August. This paper also examines the relationship between summer and winter temperatures and cloud cover, and their effect on optimal tilt and overall PV performance.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117045963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a NZEH design using photovoltaic (PV)-based distributed energy generation and multi-functional variable refrigerant flow (VRF) systems with electric and thermal energy storage systems. Simulation-based NZEH performance evaluation is conducted based on case studies under various US climate conditions. To develop a validated NZEH simulation model, the net-zero energy residential test facility (NZERTF) constructed by the US National Institute of Standards and Technology (NIST) is used for benchmarking the NZEH reference model. Changes in monthly energy consumption and on-site power generation before and after the VRF application are analyzed to capture the potential impact of the VRF system application for the NZEH design. This study shows that the alternative NZEH design with the proposed VRF and electric and thermal energy storage systems can achieve around 13% through 32% of cooling energy reductions under different US climate conditions. With the proposed VRF system, the savings potential of domestic hot water energy consumption is significant up to 90% reduction compared to the original NZEH before the proposed VRF and energy storage systems were considered.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132211045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
