Numerical simulation of solidification inside a cavity based on the enthalpy formulation

Numerical simulations are conducted to study the solidification problem with natural convection inside a rectangular cavity. The cavity is cooled on one vertical wall and is kept adiabatic at other walls. Constant temperature or constant heat flux boundary conditions are applied at the cold wall. Th...
