Abstract
Pulsatory or oseillatory gas flows in micro-channel are obsorved in some engineering devices and biological cases. One of the typicral cases is the oscillatory air flow in bronchiole of human lung. The mechanism of gas transfer and diffusion in it has nut been clarified in detail. As the first approach of the subject. oscillatory flows in straight and T-shalred micro-channels have been measured by PIV at different phase of the oscillation in order to eslablish the fundamental technique of PIV measurements on oscillatory air flow in a micro-channel and the techniques of tracer particle suspension. illumination. image capturing and so on have been investigated in this report
