Outline of Final Research Achievements

Methods to evaluate risk of health hazards by hazardous substances is developed in a cross sectional way from human scale to landscape scale. Air mixing promotion of turbulence condition which is one of characteristics in flow field is focused. Slipstream changes turbulent transition by exfoliation on the moving bluff body boundary in a steady condition. Relational expression to evaluate a turbulence field is developed from the viewpoint of assuming that bluff body virtual work rate equals to energy converted.
