Paper Title
Liquid Film Behaviors of Oscillating Slug Flows

Abstract
Liquid film thickness is an important parameter for predicting boiling and condensation heat transfer coefficients in two-phase slug flow. In the present study, liquid film thickness of oscillating slug flow in a capillary tube is experimentally investigated.Circular tube with inner diameter of 1 mm is used for the test tube, and water and ethanol are used as working fluids. The laser focus displacement meter (LFDM) is used to measure the initial liquid film thickness. Indexterms - Slug Flow, Capillary Tube, Liquid Film Thickness.
