ON A PROBLEM OF HEAT TRANSFER CONTROL IN A MEDIUM WITH PHASE TRANSITION
The problem of controlling the process of pathological tissue freezing to a predetermined depth with the required speed is solved. The process being simulated is characterized by the presence of the phase transition boundary that moves according to a certain law. The problem is solved by the method of front tracking to a grid node using the implicit difference scheme. The calculations showed the nonlinear dependence of control function on time when the phase boundary moves at a constant speed
