Abstract

A specially designed in;ector using electric conductivity was used to measure the liquid film thickness exactly, The measurement conducted through the precise calibration, accuracy is demonstrated in comparison with the previous theory and the results using other measurement method. The variation of internal flow and stability are examined through the variation of liquid film thickness by the time. The tendency of liquid film thickness for geometric parameters was examined by the precise measurement.

정확한 액막두께 측정을 위해 전기전도도를 이용한 장치를 제작하였다 정밀한 calibration을 통해 측정을 수행하였으며 기존의 이론식 및 다른 측정 방법을 이용한 결과와 비교해 보았을 때 정확성이 입증되었다. 시간에 따른 액막두께 변화를 통해 내부 유동의 변화 및 안정성도 살펴볼 수 있었다. 정확한 측정을 통해 기하학적 형상에 따른 액막두께의 경향성도 파악할 수 있었다.
