The two-zone models are seen as interesting tools for engine simulation. The two-zones, spatially homogeneous, are set during the combustion process. Such models take into account an interface of infinitesimal thickness for the separation between zones. The success of this simulation approach depends on the accuracy of the heat transfer model. Models of heat transfer, in turn, aim to obtain the heat transfer coefficient from the combustion gases in contact with the cylinder walls. Several heat transfer correlations from the literature can be used to obtain the heat transfer coefficient. Eichelberg correlation, which consider natural convection of the combustion gases, along with Woschni, Hohenberg, Sitkei and Annand correlations, which consider forced convection of those gases, were compared in search for the best fit to the experimental data.
