Turbulent Flow through a Rotating Curved Duct with Reynolds Stress Model to Automatically Sencer the Presence of a Wall

벽면감지장치를 가지는 RSM에 의한 회전하는 곡관 내 난류유동

In this study, the characteristics of the three-dimensional turbulent flow in a rotating square sectioned $90^{\circ}$ bend were investigated by numerical simulation and experiment. In the experimental study, the characteristics of a developing turbulent flow are measured using hot-wire anemometer to seize the rotational effects on the flow characteristics and to compare the results of computational simulation with Reynolds stress model. Each refinement is shown to lead to an appreciable improvement in the agreement between measurement and computation.
