Model geometry

We calculate the movement of a compressed bubble in water for 0.5 seconds. The bubble, which is initially compressed, begins to expand when the calculation starts. A no-slip condition is set for the region "walls" at the boundary of the analysis domain.

The physical properties of the water and air phases are specified in the file "constant/thermophysicalProperties.*".

The meshes are as follows, and the number of mesh is 1024000.

Meshes

The calculation result is as follows.

Volume ratio of water 0.5 isosurface

Volume ratio of water 0.5 isosurface at initial time

Volume ratio of water 0.5 isosurface at 0.5 sec

Volume ratio of water 0.5 isosurface at 0.25 sec

Volume ratio of water 0.5 isosurface at final time
