音響インピーダンス整合による衝撃波及び膨張波の生成と収束に関する研究

抄録

In the previous study, the collateral damage area was evaluated for the electrically induced bubble injector (needle-free injector) which was invented in our laboratory. It was confirmed that the input power is closely related to the depth of the injection area. However, the perforation depth of conventional bubble injector is limited as general use of injector. Therefore for the present study, evaluation and amplification of shock wave and expansion wave which are generated in cavitation and reflection phenomena is carried out. Also, the reflector to focuse shockwave is designed and fabricated to amplify the injection performance of bubble injector.
