A numerical model based on the arbitrary Lagrangian-Eulerian method (ALE) is introduced to investigate the hydrodynamics and the heat transfer of an elongated vaporized bubble in a microchannelin detail. The Navier-Stokes equations along the energy equation are solved in ALE description as a single fluid. The finite element method is used to discretize the equations. In simulations, the nucleated bubble comes in contact with superheated water and starts growing.
