Optimizing bidirectional impulse turbines for thermoacoustic engines
The Journal of the Acoustical Society of America, 2020 The design of a bidirectional impulse turbine to convert thermoacoustic power into electricity is experimentally optimized. The turbine efficiency is measured for rotors with and without a shroud ring and for a varying tip clearance. Furthermore, the axial spacing between the guide vanes and rotor is varied with respect to the displacement amplitude of
