...Kiran Kumar K; Kotresha Banjara; Kishan Naik Purpose This study aims to present the numerical analysis of exergy transfer and irreversibility through the discrete filling of high-porosity aluminum metal foams inside the horizontal pipe. Design/methodology/approach In this study, the heater...

..., it studies the irreversibility caused by the flow of a hydromagnetic nanofluid past a radiated stretching sheet by considering different shapes of TiO₂ and Cu nanoparticles with water as the base fluid. Design/methodology/approach In this study, the authors investigated entropy production...

... of the quadrant cavity does not have any impact on the flow direction. Although the magnitude of flow velocity enhances, the sidewall plays a decision-making role in the formation of a single circulation vortex. It also shows that thermal entropy production is the main cause behind thermodynamic irreversibility...

... presented for calculation of important functions (f and Nu). Outputs reveal the impacts of fin height (HF), number of fin (NF), inlet temperature (T_in) and velocity on irreversibility, thermal treatment. Findings Surface temperature decreases by 0.498, 0.07 and 0.017% with intensify of Re, HF...
