The paper presents the results of a numerical study of heat transfer in an air gap between two parallel copper plates. The lower plate is heated, and the upper plate is cooled by convection. The study was conducted using the Finite Element Method (FEM), including the ICFD (Incompressible Computational Fluid Dynamics) method for modeling air flow and heat transfer. The problem statement and mathematical model are presented. The main attention is paid to the description of the ICFD method and its key algorithms for solving the Navier–Stokes equations for an incompressible fluid. A series of computational experiments has been carried out, including the analysis of both natural convection and forced flow. The influence of the type of flow and boundary conditions on the characteristics of heat transfer and the formation of temperature fields in the system is analyzed.
