Abstract:
Three-dimensional flows in sudden expansions of rectangular channels have been investigated. In this research, CFD simulation model (FLUENT6.2) is used. The k-ε turbulence model is used to simulate turbulence. Desired canal with coarse, medium and fine mesh size is selected for simulation. The results in canal with sudden expansion showed that the vortex formed by coarse mesh size and number of iteration more than 400 is asymmetric and for small and medium mesh size is symmetric. In order to analyze experimentally and numerically more closely, the pattern of flow in a flume with sudden expansion is investigated. Results showed that, asymmetrical flow pattern can be viewed with some minor changes such as roughness coefficient in any part of flume.

Key words:  Flow pattern, sudden expansion, symmetric flow, , , ,
