Prediction of Turbulent Swirling Flow Using A Low-Reynolds-number Reynolds Stress Model

저레이놀즈수 레이놀즈응력모델을 이용한 난류선회류의 유동해석

In this study, numerical calculations are carried out in order to evaluate the performance of low-Re Reynolds stress model based on SSG model for a swirling turbulent flow in a pipe. The results are compared with those of k-ε model, GL model and the experimental data. The results show that low-Re Reynolds stress model and GL model give better results than k-ε model. In the region near the wall, low-Re Reynolds stress model improves the predictions. However, there is no large difference between the predictions with two Reynolds stress models.
