Abstract
In this study an approximate analytical method, known as the Von Karman-Pohlhausen method, is used to investigate fluid flow and heat transfer from cylindrical pin fins. A fourth order velocity profile in the hydrodynamic boundary layer and a third order temperature profile in the thermal boundary layer are used to obtain a closed form solution for the fluid flow and heat transfer from a cylindrical pin fin. The momentum and energy equations in the integral form are used to obtain the solution. Both isothermal and isoflux boundary conditions are applied. The results for both boundary conditions are found to be in a good agreement with experimental/numerical data for a single circular cylinder. The eects of free stream turbulence and blockage are not considered in this study. NOMENCLATURE
