Entropy generation in the Blasius flow under thermal radiation

In this work, we examine the effects of thermal radiation and viscous dissipation on entropy generation in the Blasius flow. The governing boundary layer equations for the velocity and temperature fields are transformed into ordinary differential equations with the help of suitable similarity transformation and then solved numerically with the help of the shooting method. The expressions for the volumetric entropy generation rate and the Bejan number are calculated for thermal radiation. The effects of various physical parameters on the entropy production number, average entropy and the Bejan number are studied through graphs using velocity and temperature profiles. It is noticed that by increasing the thermal radiation parameter the entropy production in a thermal system can be reduced and viscous dissipation increases the entropy production.
