TL;DR: In this paper, a phase change material (PCM)-enhanced solar chimney is investigated with and without considering fins connected to the absorber plate based on the temperature and velocity distributions as well as airflow rate inside a room in comparison with the non-PCM chimney.

TL;DR: In this paper, a vertical triple-tube heat exchanger involving two opposite flow streams of the heat transfer fluid (HTF) was investigated and different fin configurations, fin dimensions and HTF flow boundary conditions were explored using computational studies of melting in the PCM triple tube system, and the results indicated that the melting rate and heat charging rate could be increased by 37.2 and 59.1% in the case of staggered distribution.

TL;DR: In this article , the authors investigated the impact of modifying the fin geometric characteristics and distribution patterns in various spatial zones of the heat exchanger, and found that changing the fin dimensions with the heat flow direction results in a faster charging rate, a higher storage rate, and a more uniform temperature distribution when compared to a uniform fin size.

TL;DR: In this article, the effect of the arrangement of the tubes in a multi-tube heat exchanger was examined during the solidification process with the focus on the natural convection effects inside the phase change material (PCM).

TL;DR: In this article , the impact of design modifications on the thermofluidic behavior of a phase change material (PCM) filled in a triplex tube containment geometry was analyzed.
