| Outline of Final Research Achievements |
Fundamental research on a prompt gas exchange technique in human lung with the super high frequency oscillatory flow has been carried out in the present investigation. The present technique has been utilized the 10 times high frequnecy for air driving in the human airway. This friver was developped by using the past technique that was comleted in the acoustic compressor technology. The air was driven with high frequency of velocity amplitude at the open exit. Also, the whole bronchus model has been equipped for air flow observation. With numerical simulation, it was confirmed that the high frequency driving has an advantage for air exchange. In the present research, the raking effect that plays an important role for the gas exchange in deep region of the lungs has been discovered esperimentally and numerically.
