Graduate School of Science and Engineering, Saitama University, Saitama, 338-8570, Japan E-mail: s13dh001@mail.saitama-u.ac.jp In order to steepen the output wave shape while increase frequency of present HFOV (high-frequency oscillatory ventilation), an acoustic compressor consists of piston driver and tube with varying cross-section area has been adopted to generate the desired shocklets. Also, the results of experiment and numerical simulation have been compared with each other for verification. Due to the acceleration limit of the piston in this experiment, apparent steepening of output wave has not been achieved, whereas in numerical simulation, the distinct steepening of output wave has been observed with larger acceleration. In the meantime, the fabrication of lung model is in progress aims at observing the flow phenomena induced by shocklets with assistance of PIV and facilitating the analysis of ventilation efficiency.
