気泡の合体過程における気泡間液膜厚さの高精度測定

抄録

The coalescence of horizontally approaching twin bubbles is experimentally studied in isothermal system at room temperature. The bubbles are generated at the outlets of two tubes facing each other horizontally. Liquid film thickness formed between approaching bubbles were measured by simultaneous measurement of laser extinction method and laser interference method. This study investigates the rupture location in liquid film and the distribution of the liquid film thickness for water. The variable of the experiment are the air flow rate and the transmitted laser position. The effects of bubble approach velocity and the contact duration were investigated.
