BIR O'LCHOVLI STEFAN MASALASI

Now we will construct the simplest form of mathematical model describing phase transitions. The classic Stefan problem is a solidification and melting problem, such as the transition between ice and water.  To obtain a solution to the classical Stefan problem, the heat equation must be solved.  As mentioned above, it is needed to obtain a unique solution. It is called the variable “Stefan condition” and  given below.
