乱流モデルによる Buoyant Surface Jet の数値解析

Abstract

This paper deals with the numerical analysis of the two-dimensional buoyant surfacejets. The fundamental equations used here are the k-e model in which Launder's studyconcerning the turbulent structure of the stratified flows is involved.The brief description about the mathematical form of e-equation is given using thehomogeneous shear flow turbulence formulated by Hinze. Then it is pointed out from thenumerical results including the vertical distributions of hydraulic variables that the effectsof buoyancy term in the e-equation is quite sensitive for the stratification of water tem-perature observed in the previous experimental studies.
