This paper deals with modeling of heat flow through cylinder structural components of a marine two-stroke engine. Especially, we paid attention on simulating of temperature distribution for the wet cylinder liner. Multidimensional equations for the transient heat conduction with the Dirichlet and Fourier boundary conditions have been applied. In particular, we applied local values for the convective and radiative heat transfer coefficients using the Fourier boundary conditions determined in a space of cylinder volume and a cooling space of the cylinder. In order to determine the temperature distribution for considered spaces, we applied the radiosity method. Simulation results have been presented in the form of a temperature field for cylinder structural components depended on the crankshaft position angle. Application of the iterative calculation method for solving differential equations of energy balance allowed us for using software easy to get. We carried out all iterative computations using MS Excel spreadsheet. This way, we could decrease the simulation cost significantly.
