Sažetak
N the presented paper, the effect of the heat transfer coefficient on the cylinder combustion pressure has been analyzed. The analysis has been performed by using a simulation model that has been used for the research into the influence of multiple injections on the combustion processes and products in the cylinder of slow-speed marine diesel engines. For the analysis purpose, the combustion nul-dimensional mathematical model has been applied, which was validated by comparing the actual data measured on board a ship and the results obtained from simulations. The paper presents the results of the heat transfer influence comparison obtained by applying formulas for the heat transfer used by Annand, Eichelberg and Woschni. The results are statistically analyzed and graphically presented. The best choice is explained and suggested.
