Dispersion of Passive contaminants in a Trubulent Boundary Layer

Abstract

경계층 내에서의 난류 확산을 해석하기 위한 새로운 second-order closure방법을 개발 하였으며, 난류경계층 내에 있는 점원으로부터의 확산에 관한 문제에 적용한 결과는 실험결과와 잘 일치하고 있다.

A method to predict the dispersion of passive contaminants in a turbulent boundary layer is developed based on second-order closure approach. The dissipation of the mean scalar flux due to pressure scrambling is assumed to be inversely proportional to the plume length scale when the plume scale is small. The result appears to be in general agreement with the experiment.
