A STUDY AIMING HEAT TRANSFER COEFFICIENTS ASSESSMENT IN INTERNAL COMBUSTION ENGINES.

In the present paper has been analyzed the effect of the heat transfer coefficient on the cylinder combustion pressure. For carry out the analysis has been used a simulation model. This model 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. The combustion nul-dimensional mathematical model was validated by comparing the actual data measured on board a ship and the results obtained from simulations. The paper purpose is to presents the results of the heat transfer influence comparison obtained by applying formulas for the heat transfer used by Woschni, Annand and Eichelberg. The results are statistically analyzed and graphically presented. [ABSTRACT FROM AUTHOR]
