✦ Synopsis

A study is made of source type diabatic (nonadiabatic) flow of a viscous, heat conducting perfect gas in a conical nozzle. For such a flow a class of exact solutions to the Navier-Stokes equations is possible provided the transport properties vary as the n-th power of the absolute temperature. It is found that for a given wall angle, wall temperature, and internal heat source (sink) strength, solutions of this type are possible only for certain combinations of centerline Mach number, Reynolds number, ratio of specific heats, and Prandtl number. Some examples of calculated velocity and temperature profiles are presented for the special case where the viscosity and thermal conductivity vary as the square root of the absolute temperature.
