Steady natural convection flow on a horizontal circular disc with transpiration

Abstract

The present study deals with the effects of transpiration (either suction or blowing) on skin friction and heat transfer coetlicicnls for the steady laminar free convection boundary-layer flow generated by heated horizontal circular disc, The Boussinesq approximation is employed firstly to deal with the two possible steady cases. Secondly, the numerical solutions afC displayed for different values afthe established parameters.
