This study aimed investigates on the effects of buoyancy driven unsteady channel flow on entropy generation.The study intended to develop flow model for a case of nanofluid in a channel, determine the effect of different parameters on velocity, temperature and entropy generation. The obtained results reviled that Alumina-water nanofluid tends to raise the velocity than Copper-water nanofluid. Furthermore, the study indicated that the temperature is subjected to decrease with the increase in . Also the results show that the entropy generation rate decreases with an increase in nanoparticle fraction ( ), the vice versa results is observed when increasing an Eckert number (Ec).
