| Research Abstract |
Gas-liquid two-phase flow is encountered in many industries, including flow near nuclear fuel rods in boiling water reactor(BWR). Especially dryout of water film occurs at the thin base film between two successive disturbance waves. Therefore, it is important to clarify the detailed behavior of the disturbance wave. In previous studies, many experiments were performed under atmospheric condition. However the properties of liquid and gas under atmospheric condition are quite different from those of a BWR operating condition(7MPa, 285C). Therefore, in the present study, HFC134a gas and ethanol liquid, whose properties are similar to those the BWR operating conditions are used as the test fluids at comparatively low pressure and low temperature (0.7MPa,40C). In this paper, the influence of gas-liquid properties on the liquid film thickness is reported.
