Abstract:
The burning rate of hydrogenair premixture on mesoscale is mainly determined by its chemical reaction rate. So a Laminar Finite Rate Model, the gas phase reaction mechanism for the combustion of hydrogenair mixture which consists of 19 reversible elementary reactions and the dynamic mesh method are adopted to simulate the combustion of hydrogenair mixture in a mesoscale IC engine which operates a quasi gas power cycle under ultrahigh combustion load. The combustion of hydrogenair mixture on mesoscale in the micro combustion chamber with moving boundary can be stable. The complete thermodynamic process of heat addition, internal energy increasing, and a boundary work output producing during expansion can be perfectly achieved in the closed combustion system of the mesoscaled IC engine igniting the hydrogenair mixture by wire surface of high temperature. However, running parameters such as cycle period, initial pressure and fuel/air ratio have complex effects on the hydrogenair combustion of micro closed container with moving boundary.
