두 원형분류에 의한 45° 충돌분류의 혼합유동구조에 대한 난류모델 평가

다국어 초록 (Multilingual Abstract)

In this paper, the CFD analysis using various turbulent models has been performed to evaluate which type of turbulent models can predict well the mixing flow structure of 45° impinging round jet. This CFD analysis has been carried out through the commercial Fluent software. As a result, any of turbulent models cannot predict the experimental results definitely all over the flow range. However, as compared with the experimental results, the turbulent model of realizable(RLZ) k-ε only predicts well in the limited range between X/X?=1.1 and X/X?=2.0.
