Default moving boundary / mesh
Posts: n/a
hi, I'd like to model the heat / mass transfer between a bubble and its boundary layer. it seems that this is a moving mesh / boundary problem because the boundary layer is affected by the changing bubble size. Can someone advise me on how to model / code this moving boundary problem. this is a 1-D spherical coordinated problem. Any advice is highly appreciated. Thanks.

In similar cases, I used the ALE governing equations coupled with the level set method providing the interface location. The interface grid was treated in Lagrangain way while other grids were adjusted uniformly as much as possible.
