Grooves, dimples, protrusions, and corrugations are being used to improve the inside and outside surfaces of tubes and channels. Different channels are being used in the electronics such as the channels in the microprocessor for heat exchange. These channels are differentiated based on their shapes and coolants used in them. These heat channels minimize the losses that occurred due to the heating up of devices. This research presents a numerical study and comparative analysis of heat transfer and flows characteristics with different pipe geometries with the addition of nanoparticles. A simulation-based software is used for changing the geometry of channels and concentration of nanoparticles in flowing fluid to make a comparative analysis of straight and dimple-protrusion overlapped technology. The rate of heat transfer is used to make this distinction. The nanoparticles of Copper oxide with a concentration of 2% and 4% are added in fluid and a maximum increment of 15% is obtained in Nusselt Number.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129100970","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 challenge in designing and scaling up the electrochemical systems lies in the selection of electrode material and suitable operating conditions. This study investigates the effect of three operational variables including treatment time, current density, and inter- electrode spacing on the quality parameters of drinking water. The results show that the technique effectively reduces the level of suspended and dissolved solids. Increasing either operating time or current density and decreasing the interelectrode spacing has a beneficial role in the treatment performance. Further, the ions produced during the electrolysis process can disinfect the biological contaminants thus making the water suitable for drinking purposes. The need for stable electrode materials for the successful application of the treatment method has also been discussed.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"9 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128258123","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}

However, global warming is one of the today’s biggest concern which is driving the world towards adoption of environmentally friendly products and processes. In this regard, many of the widely used refrigerants such as R22 are on the verge of being phased out due to their global warming potential (GWP) and ozone depletion potential (ODP). Hence, there is dire need to find refrigerants with not only low GWP and ODP but also promising performance. In this paper, thermodynamic analysis of a combined ORC-VCC system powered by low-grade energy source is presented. The system is modelled in Engineering Equation Solver (EES) and its performance is assessed using two parameters: Cooling Capacity (CC) and Coefficient of Performance (COP), calculated under complete refrigeration mode, i.e., all the turbine power output is consumed by compressor. Three working fluids with low GWP and ODP from different working fluid categories are selected: R290 (hydrocarbons), R152a (hydrofluorocarbons) and R1234yf (hydrofluoroolefins), and a comparative thermodynamic performance analysis of selected working fluids against R22 is conducted. From the results, it is concluded that both R152a and R290 are potential candidates. From performance point of view, R152a, with low but some GWP, is a high performing working fluid, having COP lower than that of R22 by approx. 2.8%. Whereas, from environmental perspective, R290 has no GWP, provides the highest CC under same operating conditions, and has COP lower than that of R22 by around 8.5%.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129814182","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}

As the penetration level becomes higher, numerous challenges appear regarding the impacts it has on the power system especially the transmission network. The evaluation of these impacts is beneficial for power system operation and planning. Power system operators throughout this era have developed numerous formulations and strategies to capture the impacts of the integration of wind power technologies. In this paper, various impacts of high penetration of wind power on the transmission network have been studied and an overview of problems concerning large-scale integration of wind farms is presented. A single period AC Optimal Power Flow (AC OPF) is performed in MATPOWER on modified IEEE-118 bus system under different wind penetration levels to analyze the impacts on voltage profile, transmission congestion, locational marginal prices (LMPs), transmission losses, and generation cost of the system. The AC OPF formulation is described and simulation results from MATPOWER are also presented and discussed.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129499358","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}

Global warming is the main detrimental effect of these emission products, and it becomes essential to mitigate the effect of emissions to the environment. Integrated gasification combined cycle (IGCC) technology operating in flexible mode of co-generation can play a key role in mitigating the air pollution and improving the overall efficiency of the plant. Thermal and economic analysis of the IGCC co-generation system help make fine decision to run the IGCC plant in flexible mode for co-generation of fuel and chemicals along with power.In this work, the IGCC co-generation system has been simulated using dry-coal feed gasifier (i.e., Shell gasifier) under thermochemical equilibrium with the Gibbs free energy approach in Aspen Plus®. Thermal and economic models for the coal similar to Pakistani coals have been developed. Thermal and economic analysis on the IGCC co-generation system developed for simultaneous production of methane, ammonia and electricity has been performed. Performance indicator like cost of electricity (COE) of co-generation system has been calculated by considering methane and ammonia as a co-product and subtracting revenue credits from the annual operating cost. Results show that, COE for IGCC 100% power is 133.6 $/MWh in comparison to IGCC co-generation with value of 152.4 $/MWh. In the end, change in CO2 emission rate in co-generation system has also been investigated. Annual CO2 emission in IGCC co-generation system is 352,314.4 tons/year in comparison to 433,449.6 tons/year for IGCC 100% power design.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131164210","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}

Although conventional power system is experiencing a notable transition from the centralized supply-side energy management system to decentralized generation and demand-side load management system certainly due to the integration of hybrid energy systems to the local grids yet the shortfall in supply and energy demand gap resulted into large scale electric load-shading problem in all cities of Pakistan from last few years. This paper discusses a real-time load management system integrated with a hybrid energy system as a source i.e. grid-tied photovoltaic (PV) system, stand-alone PV system, wind-turbine, local grid and aims to have a customer control overload appliances in peak and off-peak hours, update them for hourly units consumption and also shed the unnecessary loads according to user-set priority and demand. The hybrid energy system and load end is interconnected to the programmable logic controller (PLC) and are also controlled by using PLC. According to the specified site and load demand discussed in the paper, it has been found that by implementing the proposed load management system approach average of 82 units of electricity can be saved in peak hours, and similarly the average amount of 4.875 Rs/KWh can also be saved for specified time dictating that proposed smart strategy can prove to be fruitful to combat electric load problem on large scale in Pakistan in future.","PeriodicalId":374012,"journal":{"name":"2021 4th International Conference on Energy Conservation and Efficiency (ICECE)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128319359","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}
