Bulk Flows - Squish, Swirl and Tumble - and Turbulence in IC Engine Cylinder v5
Original language description
Detailed description of K-k-l model for squish, swirl and tumble bulk flows with influence of axial gas motion in a cylinder. Geometry available for bulk eddies according to different shapes of combustion chamber in dependence of piston stroke. Cummulation of swirl and tumble motion during inlet stroke using results from flow-box test. Dissipation of bulk flow kinetic energy due to friction in boundary layers and momentum mixing is refdlected in source term of turbulent kinetic energy. k-epsilon model for turbulence dissipation. Development of bulk flow due to vortex dimension changes during compression and start of expansion with similar K-k-epsilon model of turbulence.
