Abstract
This paper aims to investigate the entropy generation analysis for the free convection film condensation on an inclined porous elliptical tube. An analytical approach to study the effects of various working parameters, including Rayleigh, Darcy, Brinkman numbers and tilt angles on the entropy generation rate is performed. Although dimensionless heat-transfer coefficient is enhanced with an increase in tilt angles and Rayleigh group parameters, entropy generation number is augmented. Two main irreversible factors-finite-temperature difference heat transfer and condensate film flow friction associated with porous permeability affecting the total entropy generation rate are investigated.
