| Abstract: | Using Poisson equation, 3D body-fitted grids are generated based on multiple blocked structure technology. ALE method is used to simulate the 3D steady turbulent flow field in a 3-way branch pipe whose section is cylindrical. The computing results are compared with the measured data obtained by LDA. The computing results have a good agreement with the measured ones and can show the flow features of the pipe. |
