要約

A new calculation procedure has been described for heat transfer in uniform-property turbulent boundary layers. The method consists of the solution of the integral momentum and kinetic-energy equations to yield the properties of the hydrodynamic boundary layer, followed by the solution of two similar integral equations for the thermal boundary layer. Two-component velocity and temperature profiles are used; and the shear stress and the heat flux in the boundary layer are connected with the profile parameters by use of a mixing-length hypothesis. The predictions of the theory are compared with available exact solutions, and with a number of experimental data; the agreement is satisfactory when "laminarisation" is absent.
