要約(英語): Mechanical behavior of micro-scale normal shock and shock train were observed to demonstrate its usefulness for compression process of a micro-scale radial wave rotor. The micro-scale radial wave-rotor consists of multi-rotational cells. The mechanism of compression by shock wave is a key issue of increasing the internal pressure of the cells required for the turbo-compression of MEMS turbomachines. However, the mechanical behavior of the shock wave used for the MEMS turbo-compression has not been investigated in micro-scale domain. Therefore, we demonstrate the shock wave formation by using a micro-scale supersonic wind tunnel to verify the conceptual design of the micro-scale radial wave-rotor. It was found that compression process due to the shock train may be generated in the micro-scale straight duct. However, its static pressure recovery is much smaller than that of the isolated normal shock.
