Impact of surface texture on entropy generation in nanofluid

We consider a heat transfer augmentation problem to minimize the entropy generation by assuming boundary-layer flow of nanofluid over moving wavy surface. The demonstrates great potential in enhancing process due its high thermal conductivity. famous Tiwari and Das model has been used present article. Two types water based nanofluids containing Cu Fe3O4 nanoparticles are considered. Moreover, surface texture is taken be sinusoidal improve contact. governing equations transformed into system non-similar PDE using suitable dimensionless variables solved Keller-Box method. effects involved parameters like amplitude wavelength ratio, group parameters, volume fraction on total number Bejan analyzed graphically. It showed base more effective lessen production as compared nanofluid.
