A thermosyphon-type heat pipe constructed of copper with 20-mm internal and 18-mm external diameters was used in this experimental work. The fulfillment of the heat pipe was examined by operating three separate operating fluids: distilled water, hybrid and mono-magnetic nanofluids. The fluid was injected into the system with a filling ratio equal to 1/3 of the total volume of the heat pipe for all individual experiments. Practical analysis was performed under three distinct input heats and two different nanofluid weight percent as an operating medium in the evaporator section and three different coolant mass flow rates in the condenser area of the system. Wall temperature fluctuations, index factor (efficiency), Nusselt number, and thermal resistance magnitudes were obtained for distilled water, iron oxide-ferric oxide hybrid magnetic nanofluid, and nickel ferrite mono-magnetic nanofluid for each experiment. The highest improvement rates in heat transfer ability, Nusselt number, and heat pipe thermal resistance magnitude were 30.55%, 26.9%, and 61.8%, respectively, when the iron oxide-ferric oxide hybrid magnetic nanofluid was employed as an operating fluid compared to distilled water. The thermal performance of the system increased significantly with increasing the weight percent of both hybrid and mono-magnetic nanofluids. Basically, the efficiency of the system was improved by 3.92% by increasing the weight percent of the hybrid magnetic nanofluid from 0.5 wt.% to 1 wt.%.","PeriodicalId":50408,"journal":{"name":"Heat Transfer Research","volume":"110 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67475074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two copper oscillat-ing heat pipes filling with water and acetone respectively were investigated by a neutron imaging technique to visualize the fluid motions in the oscillating heat pipes. Temperatures on the surface of the oscillating heat pipes were measured while neutron images were taken simultaneously. Al-gorithms to determine the degree of activity and the interface passing count were developed to analyze fluid motions quantitatively from the neutron images. Then, the degree of activity and the interface passing count were compared with temperatures. The results showed that there are patterns of temperature change before and after start-up of the oscillation motions. The acetone oscillating heat pipe showed better thermal performance at a similar heat input, while the water oscillating heat pipe showed better thermal performance at a similar degree of activity. Interfaces in the acetone oscillating heat pipe oscillate more frequently and travel further. A virtuous circle is formed between sensible heat transfer and latent heat transfer for better thermal performance. Low latent heat at low heat input, low viscosity and high thermal conductivity are preferred for the working fluid to achieve better thermal performance.","PeriodicalId":50408,"journal":{"name":"Heat Transfer Research","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135596799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research investigates the use of an East-West (EW) reflector and coal cinder additive (CC) to enhance the energy efficiency of a trapezoidal salt gradient solar pond (SGTSP). The study involved designing, fabricating, and analyzing the SGTSP systems with EW and CC, compared to the standard SGTSP system, from an energy point of view. Additionally, the study provides shading area analysis based on the SGSP system's slant angle, offering valuable insights into its performance for low-grade heat source thermal applications. The findings indicate that the EW reflector significantly increased the average solar intensity by 33.2%, while the addition of coal cinder additive raised the average temperature of the lower convection zone by 24.1%. The SGTSP system with EW reflector and coal cinder additive (SGTSP-EWR&CC) demonstrated a maximum average temperature of 83.85°C and a 42% higher energy efficiency in the lower convection zone compared to the conventional SGTSP system (SGTSP-C). Overall, the study showcases the potential of SGTSP as a sustainable energy system for thermal energy storage and provides practical strategies for enhancing its energy efficiency.","PeriodicalId":50408,"journal":{"name":"Heat Transfer Research","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135954037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present research work used CFD simulations to examine the impact of various parameters, such as the rib type (continuous, discreet), the arrangement type (rectangular, square and triangular) and the geometrical parameters (transversal and longitudinal pitch) on the PHE hydraulic and thermal performances. A three-dimensional 3D evaluation of turbulent flow over a plate fitted with carding tool patterns was conducted using the k-ɛ turbulence model and with a Reynolds number range of 400 to 1800. The numerical results were compared to previous experimental research to validate the dependability of the technique, and a mesh independence analysis was performed to confirm the precision and the accuracy of the CFD method. The results show that CFD software Ansys can effectively predict the pressure drop across the carding tools and provide valuable insights into the fluid flow behavior within the system in terms of calculating the thermal hydraulic performance parameter THPP and the thermal effectiveness ɛ. The ultimate goal of this research work was to identify the ideal arrangement with the highest heat transfer rate and the lowest pressure losses in terms of determining the best THPP. Compared to the conventional PHE chevron type, the thermal performance of the novel PHE design was enhanced by 25.63 % and 54% in terms of non-dimensional parameters ɛ and THPP, respectively.","PeriodicalId":50408,"journal":{"name":"Heat Transfer Research","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136209072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
