Although thermally driven phase change phenomena have an essential role in large‐scale and small-scale applications as an efficient heat transfer mechanism, their simulation is still in its infancy. One of the main challenges in CFD modeling of this phenomenon is locating the interface position. Default formulation for simulating phase change uses the Volume Of Fluid (VOF) method as the interface description method. The main drawback of VOF is the smearing of the interface and the difficulty in obtaining sharp interfaces between the phases, which may lead to spurious flows and inaccurate results.  In my project, to avoid smeared interfaces and have accurate results in the simulation of thermally driven phase change phenomena, we will extend a new formulation (a solver in OpenFOAM) for their CFD simulation, being capable of using two more accurate interface description methods (CLSVOF and isoAdvection) and adaptive mesh refinement.
