Journal ArticleDOI
Effect of obstacles on thermal stratification in hot water storage tanks
TL;DR: In this paper, the effect of using different obstacles on thermal stratification in a cylindrical hot water tank is analyzed numerically using both experimental and numerical results, and the results indicate that placing obstacle in the tank provides better thermal stratified compared to the no obstacle case.
Journal ArticleDOI
Heat transfer enhancement in a tube using circular cross sectional rings separated from wall
TL;DR: In this article, a numerical study was performed for investigating the heat transfer enhancement in a tube with the circular cross sectional rings and the results obtained from a smooth tube were compared with those from the studies in literature in order to validate the numerical method.
Journal ArticleDOI
Improved thermal stratification with obstacles placed inside the vertical mantled hot water tanks
Dogan Erdemir,Necdet Altuntop +1 more
TL;DR: In this article, the authors investigated the thermal stratification of vertical mantled hot water tank by placing different obstacle inside the tank and found that the obstacle placed inside a tank enhanced the thermal Stratification.
Journal ArticleDOI
Effect of ambient conditions on the first and second law performance of an open desiccant cooling process
TL;DR: In this article, an open desiccant cooling process is presented and applied to ventilation and recirculation modes of the system operation, where ideal operating characteristics based primarily on the first law of thermodynamics are assumed for each component.
Journal ArticleDOI
Effect of water inlet velocity on thermal stratification in a mantled hot water storage tank
TL;DR: In this paper, the thermal stratification in a mantled hot water storage tank is analyzed numerically for different water inlet velocities, and the results obtained from the numerical analysis have shown very good agreement with the results from previous works.
