Temperature field in non-Newtonian flow over a stretching plate with variable heat flux (Q1116820)

This study deals with the temperature distribution in a viscoelastic fluid of Walters' liquid B model over a horizontal stretching plate. The velocity of the plate is proportional to the distance from the slit and the plate is subject to variable heat flux. The results are expressed in terms of Kummer's functions. Several closed-form solutions for specified conditions are presented. The effect of the viscoelastic parameter \(Ko^*\) and the heat flux parameter \(s\) on the temperature field is also studied. In addition, the solutions of a linearly stretching plate in a Newtonian flow with variable surface heat flux are also obtained. When \(Ko^*=0\) and \(s=0\), the solutions reduce to the published results.
