Computation of the Turbulent Flow in an Internal Combustion Engine During CompressionSource: Journal of Fluids Engineering:;1981:;volume( 103 ):;issue: 001::page 75Author:P. S. Bernard

Abstract: A set of closed dynamical equations for the mean and variance of the turbulent vorticity field are used to study the piston driven flow in a two-dimensional model of an internal combustion engine cyclinder during the compression stroke. A dominant feature of the flow is observed to be the development of large corner vortices. In their vicinity intense production of turbulence occurs which locally greatly exceeds that resulting from the compression of intake generated turbulence. A comparison of the flow field at two strokes to bore ratios is made.
