CONVECTIVE HEAT-TRANSFER FROM A CIRCULAR-CYLINDER UNDER THE EFFECT OFA SOLID PLANE WALL

The purpose of this investigation is to study the convective heat tran sfer from a horizontal circular cylinder under the effect of a solid p lane wall. The full Navier-Stokes and energy equations for two-dimensi onal steady flow are solved by a finite element method. The variations in surface shear stress, local pressure and Nusselt number around the surface of the cylinder as well as the predicted values of average Nu sselt number, location of separation and some flow and temperature fie lds are presented. It is found that the average Nusselt number and dra g force increase as the gap between the cylinder and the wall is incre ased.
