Abstract

Wave rotor is expected to improve the performance of micro gas turbines drastically In the wave rotor design the rotor speed is determined principally by the tube length Therefore a longer tube is preferable for miniaturized wave rotors to avoid the difficulty in bearings and lubrication system while it may yield thicker wall boundary layer shock wave dissipation and so on In the present study an experimental apparatus was built to visualize the wave rotor internal flow dynamics in a narrow tube by schlieren method and Laser Doppler Anemometry In addition different lengths of the tube were adopted and compared to investigate the effect of wall friction Finally 2D numerical simulation was performed and the results were compared with those of experiments
