Abstract: a b s t r a c tRapid Compression Machines (RCMs) often employ creviced pistons to suppress the formation of the rollup vortex. However, the use of a creviced piston promotes mass transfer into the crevice when heat release takes place in the main combustion chamber. This multi-dimensional effect is not accounted for in the prevalent volumetric expansion approach for modeling RCMs. The method of crevice containment avoids post-compression mass transfer into the crevice. In order to assess the effect of the cre…
