In dual-fuel (DF) engines, a high-reactivity fuel (HRF) ignites low-reactivity (LRF) premixed with air. Identification of the combustion mode after autoignition in DF engines different combinations and under various mixture stratification levels is crucial importance since may affect engine performance emissions levels. However, to avoid expensive computational or experimental tests for initial...

Thermal explosion problem for a medium with oscillating ambient temperature at its boundaries is considered. This is a new problem in thermal explosion theory, not previously considered in a distributed system formulation, but important for combustion and fire science. It describes autoignition of wide range of fires (such as but not limited to piles of biosolids and other organic matter; stora...
