Temperature field at nonlinear gas oscillations in a rectangular channel

The effect of low-intensity forced oscillations of a gas on the temperature field in a rectangular channel is studied. A nonuniform temperature distribution along the side wall of the channel during resonance was revealed. The maximum heating of the gas is observed near the piston and the closed end, which is due to the work of compression forces in the pressure antinodes at the ends of the channel, which form in a standing wave. An increase in the average temperature in the channel with increasing duration of experiment in the resonance mode of gas oscillations was revealed.
