Abstract
This study is focused on the local entropy generation of steady two‐dimensional symmetric flow past a parabolic cylinder in a uniform stream parallel to its axis. The effect of both Reynolds number (Re) and temperature difference between the cylinder wall and the freestream (ΔT) on thermal, viscous, and total entropy generation is investigated for different values of Prandtl number (Pr) and Mach number (Ma). It was found that the thermal entropy generation increased as the temperature difference increased, while the viscous entropy generation decreased as Reynolds number increased. The results also showed that increasing Prandtl number or Mach number increased both the viscous and thermal contributions to the entropy generation.
