Abstract
Subsonic motion of heated ideal gas in a cylindrical channel with constant heat flux through the wall is considered. It is shown that consideration of friction forces on the wall results in that the position of gas temperature maximum caused by thermodynamic cooling at expansion depends on the heat flux, the friction coefficient, and the Mach number value at the inlet channel section. The condition under which there is no temperature maximum in the channel is found.
