Baroclinic 토크에 의한 벽근처 난류의 수정

다국어 초록 (Multilingual Abstract)

We investigated modification of inhomogeneous turbulent channel flow imposed on the thermal stratification using direct numerical simualtion. Typical length scale of vortical structures becomes smaller under stratification, whereas the length scale associated with temperature variation becomes larger. Both streamwise and spanwise components of baroclinic torque showed strongly intermittent behaviors. It was found that both increased small sized structures and changes in inclination angle of coherent structures are closely connected with the baroclinic torque. As the Richardson number increased, the angle of strong vortical structures make with the wall increased in buffer layer, while decreased in the outer layer.
