본 연구에서는 관내분류에 관한 수치 해석을 Reynolds응력 모델 즉 5방정식 모델을 사용하여 흐름의 특성을 구명키로 하였다.
Fully Reynolds Stress model is applied to predict recirculation pattern, velocity and Reynolds shear stress distributions in a circular jet coaxially confined in a round pipe. It is found that the generation of velocity region depends on Curtet number(Ct). It is also found that the Reynolds shear stress and velocity distributions in the inital jet region depend strongly on the Curtet number up to about X/D = 2.0 but they are almost independent of the Curtet number further downstream.
