MIXED CONVECTION AROUND AN AXISYMMETRICAL BODY

The authors study momentum and heat transfer in the boundary layer sur rounding an axisymmetric body in the case of an established laminar ne wtonian flow. An ascendant free convection, a rotary convection and an axial forced convection are taken into account. The authors propose t wo computer programs for the determination of the velocity and tempera ture fields in the boundary layer. The first is numeric and users the Gortler's development. These programs also give the local values about Nusselt number and friction coefficients on the body. An another prog ram is used to make the calculation of the flow field at the outside o f the boundary layer using a method singularities. They show the compl ementarity of the two methods.
