Radiation effects for the Blasius and Sakiadis flows with a convective surface boundary condition

摘要

This study aims to analyze the effects of thermal radiation on the laminar boundary layer about a flat-plate in a uniform stream of fluid (Blasius flow), and about a moving plate in a quiescent ambient fluid (Sakiadis flow) both under a convective surface boundary condition. The resulting similarity energy equation is solved numerically and the variations of dimensionless surface temperature and fluid–solid interface characteristics for different values of Prandtl number Pr, radiation parameter NR and parameter a, which characterizes our convection processes are graphed and tabulated. Quite different and interesting behaviours were encountered for a Blasius flow compared with a Sakiadis flow. A comparison with previously published results on special case of the problem shows excellent agreement.
