Abstract
The challenging problem of the full three-dimensional Taylor bubble has been addressed by using a Conservative Level Set method in order to deal with the multiphase flow. A moving mesh is used, aiming to optimize the simulation domain. The mesh is moved as the bubble rises, so the region of study can be limited to the surroundings of the bubble, notably reducing the domain's size. This saving in the computational resources facilitates to face the Taylor bubble problem without the axisymmetric assumption. By doing so, a detailed description of the fluid field is provided, comparing the results against numerical and experimental data.
