A NUMERICAL STUDY OF ENTROPY GENERATION ON OLDROYD-B NANOFLUID FLOW PAST A RIGA PLATE

This study investigates entropy generation due to the unsteady boundary layer flow of an Oldroyd-B nanofluid past a Riga plate. The velocity, temperature and concentration fields are obtained equations solved numerically using spectral collocation method with overlapping grids. local distribution is by solving equation numerically. Sensitivity convergence analysis performed demonstrate accuracy numerical method. effect principal parameters on investigated it established that directly proportional width plate, Brinkman number, Prantl number Brownian motion parameter. It further shown inversely Eckert Deborah in relaxation time. range parameter values were from reported literature. current may have applications physics, including design both cooling heating devices.
