Abstract:
Analysis and physically/chemically based modeling through an energy-balance of the influences of the time-varying unburnt mass fraction in wall proximity and in the top land. At first, the influence of near wall zones and the top land volume on the combustion chamber in the combustion phase after reaching peak pressure shall be investigated experimentally with a focus on modeling. Based on these findings, a model to describe the near wall phenomenon of the heat release through an energy-balance shall be developed. A better understanding of the interactions between top land volume and combustion chamber is a necessary boundary condition to describe the effects of the unburnt mixture mass in the top land and to make it useable in analysis and simulation.
Focus: A better understanding of the interaction between top land volume and combustion chamber Description of the effects of the unburnt mixture mass in the top land.
