Eï¬ect of Reynolds Number and Curvature ... 7 a wide range of curvature ratio and Reynolds number. The objective of present study is to simulate of the ï¬ow pattern in 90Ë pipe bends with diï¬erent curva-ture ratio with diï¬erent Reynolds number. The details of ï¬ow pattern throughout the bend were studied.
