水平流路内水中を進む気体の形状と液の流れ(流体工学,流体機械)

抄録

The present study is concerned with numerical simulation of the movement of gas progressing with the constant velocity in a horizontal channel filled up with water. The dependence of the gas-liquid interface shape and the liquid flow in the neighborhood of the gas phase tip on the channel height and the gravity force are analyzed by the numerical simulation program FIDAP. The three cases that the height of the channel is greater than, almost the same as and less than the bubble limiting thickness are studied. The relation between the residual liquid film thickness on the wall after passage of the gas phase tip and the tip velocity is also discussed.
