Outline of Final Research Achievements

Direct numerical simulations (DNS) were performed for stably stratified turbulence and compressible turbulence. Influences of internal gravity waves and pressure waves on turbulent/non-turbulent interfaces were investigated by detecting the turbulent fluid based on vorticity or potential vorticity. A multi-particle interaction model was proposed for molecular diffusion and thermal conduction. The performance of the model was evaluated with the DNS database of turbulent planar jets. The piston jet actuator with single/multiple orifice was experimentally studied with cylinder pressure measurement and flow visualization based on the shadowgraph method. These experiments revealed the relation between the cylinder pressure and jet Mach number.
