I have experienced an unphysical decrease in temperature (should be 333,15 K the smallest value in the domain) during water entry of heated solid in a turbulent flow (realizable k-epsilon model is used) in Ansys Fluent 2020 R2. The time step size is set to 1e-5 s, and the temperature goes some very low limits (see Fig. below).
The question is: "How one can stabilize the energy equation in order to make the minimum temperature 333,15 K as is?"

Check the boundary conditions, mesh resolution and phase change settings. How does the convergence look?
