Abstract: An exhaust channel of a microturbine engine, characterized by a tapering pipe for reducing the speed at which a high-temperature gas is discharged from the turbine and ensuring that the high-temperature gas induced into a recuperator produces a uniform, low-speed flow field, with a view to preventing any noticeable vortex region from developing in the channel, minimizing the pressure loss in the channel, and enhancing the heat exchange efficiency of the recuperator.
