Convection solved problems
WebConvection heat transfer is treated empirically because of the factors that affect the stagnant film thickness: Fluid velocity; Fluid viscosity; Heat flux; Surface roughness; … Webconvection, radiation and others. Because of this, very few problems can be solved analytically and one generally has to resort to numerical analysis. The boundary element method is a numerical technique which has been receiving growing attention for solving heat transfer problems because of its unique
