Abstract

Instability of the Initial flame propagation is examined after computing the flows during three continuous cycles of an engine. Cycle-resolved large eddy simulation (CLES) is employed for these computations. First, we calculated the compressible turbulent flows during three continuous cycles in a model engine having square piston. Then, the initial flame propagation processes are calculated by using G-equation at the flow condition of TDC. Grid system of 1,000,000 points is employed. Relation between cyclic-resolved turbulence and initial flame is qualitatively examined by the computational results.
