Thermal Radiation and Thermodiffusion Effect on Convective Heat and Mass Transfer Flow of a Rotating Nanofluid in a Vertical Channel

摘要

This paper presents a numerical study of thermal radiation and thermodiffusion effect of moving wall (oscillatory) velocity on unsteady convective heat transfer flow of two types of water-based nanofluids (Cu, Al_2O_3) in a vertical channel under the influence of heat sources. Employing regular perturbation method, the momentum and the energy equations are solved analytically. The results of the fluid velocity, temperature, and concentration profiles are presented graphically and discussed for the pertinent flow parameters.
