摘要：

An analysis of combined forced and free convection heat transfer of a quasi-incompressible fluid flowing laminarly in a horizontal tube is presented. The physical properties are assumed to be independent of temperature and the heat flux imposed at the tube wall is considered to be uniform along the tube and around the circumference. The flow and heat transfer are specialized for fully developed conditions and the resulting partial differential equations are solved by a perturbation method. Approximate analytical solutions as well as average Nusselt numbers are presented graphically for a range of Prandtl and Grashof numbers of physical interest. The predicted velocity, temperature and average Nusselt numbers are compared with available experimental data. © 1969.
