Abstract
Present study is devoted to a numerical analysis of heat transfer processes inside a complex radiator system based on phase change materials (PCM) under the influence of unsteady heat generation local element and external convective cooling. The numerical solution has been implemented by the finite difference method using the enthalpy-based approach to solve the energy equation. As a result of the solution, temperature distributions and liquid flow structures for different time moments, as well as integral characteristics of the melting process as a function of time, have been obtained. The effect of the external Newtonian cooling on the melting intensity and heat transfer patterns has been analyzed.
