Abstract

A combustion chamber for use in an engine, such as a rocket engine, has an inner wall with a corrugated configuration. The inner wall is formed with a plurality of tubes for carrying a coolant. As a result of the tubular construction, the inner wall has a plurality of spaced apart crowns and a plurality of valleys intermediate with the spaced apart crowns. To enhance the rate of heat flux or transfer in the valleys, a device is installed in each valley to cause local intensification of the turbulence in the hot gas flow in an effective way. The device may take the shape of a chevron or a bump.
