To perform the simulation of fluid flow, fuel spray and combustion in an internal combustion engine, the boundary conditions in the engine’s geometry require that a temperature be specified in the internal solid/fluid interface; it is difficult to measure experimentally. To obtain the borders' temperature values, a multidimensional simulation of a single-cylinder compression-ignition engine is performed, using solid walls in the Converge CFD software, with combustion and fluid/solid conjugate heat transfer. Considering that, the time scales of heat transfer in the solid are greater than those on the fluid, in the simulation the super cycling approach is used for the solution of conjugated heat transfer problems. 25 cycles are simulated for the engine, where combustion is considered using the rate of heat release as a function of crank angle, obtained from combustion with a kinetic mechanism for n-dodecane (C12H26). In the final cycle, when the heat transfer reaches the permanent regime, the temperature is obtained as a function of crank angle for the solid walls that make up the engine, which is used as boundary conditions in new simulations.
