The Effects of Buoyancy Force on the Irreversibility of Three-Dimensional Step Flow in an Inclined Duct

Abstract: This research deals with the study of the irreversibility of three-dimensional mixed convection flow in an inclined duct with step. To reach this goal, an analysis of entropy generation is carried out according to the second law of thermodynamics. The effects of buoyancy force on the flow irreversibility are analyzed with all details. The results show that the values of entropy generation number and Bejan number are intensively dependent on the Grashof number and duct inclination angle, so that the effects of … Show more

“…So far, many different techniques have been presented by researchers to determine the rate of flow irreversibility. Among these techniques, analysis of the thermodynamics second law (entropy generation analysis) is a useful method and plays an important role in determining the optimal conditions for engineering systems (Erbay et al 2004, Atashafrooz andAsadi 2019). This analysis has been applied by many researchers to investigate the flow irreversibility in various geometries (Kooshki et al 2012, Bahaidarah and Sahin 2013, Mohaghegh and Esfahani 2016.…”
