Abstract
This study is focused on the local entropy generation of steady two-dimensi onal symmetric flow past a parabolic cylinder in a uniform stream parallel to its axis. The effect of both Reynolds number (Re) and temperature differ ence between the cylinder wall and the freestream (DeltaT) on thermal, visc ous, and total entropy generation is investigated for different values of P randtl number (Pr) and Mach number (Ma). It was found that the thermal entr opy generation increased as the temperature difference increased, while the viscous entropy generation decreased as Reynold's number increased. The re sults also showed that increasing Prandtl number or Mach number increased b oth the viscous and thermal contributions to the entropy generation.
