Influence of aspect ratio on the natural convection and entropy generation in rectangular cavities with wavy-wall

Numerical study of asymmetric and axisymmetric thermal jet with entropy generation concept

“…For their part, Boussoufi et al [13] have studied numerically the flow characteristics and entropy generation of multiple jets and succeeded in showing that, the multiple jets augments the rate of generation entropy. It was also studied by Morsli et al [14][15][16][17][18] and others differently in several areas. Where their results indicated that the rates of generation of total entropy reduce with an augment equivalent ratio and oxygen percentage in air [14], augment with Rayleigh number [15] and in position where reactions are effective [16].…”

Additionally, Ries et al [17] studied the production of entropy in the turbulent flow near the wall inside a general heat exchanger from air to air, where ABSTRACT -In the current investigation, numerical study of a thermal jet of asymmetric (rectangular and elliptical) and axisymmetric (circular) geometry was investigated with variable density to verify the impact of the ratio of density and geometry on the generation of entropy.…”
