THEORETICAL AND EXPERIMENTAL VALIDATION OF HYDROGEN FUELED SPARK IGNITION ENGINE

In modern research, simulation has become a powerful tool as it saves time and also economical when compared to experimental study. This paper deals with a comprehensive model of a spark ignition hydrogen fueled engine. Woschni's heat transfer co-relation is used by this model for predicting the heat transfer in the engine. Two zone combustion model has been opted for simulating the combustion process. Two zone models account for the combustion chamber geometry and for the presence of burnt and unburnt gases. The results are compared with the experimental data and it is found that there was a good convergence of results. The engine efficiency and power has been slightly over predicted because dissociation has not been included in the model
