NUMERICAL SIMULATION OF 3-D CORNER FLOWS IN A CIRCULATING WATER CHANNEL

摘要

In this paper, a Navier-stokes procedure was developed based on a finite volume method to simulate corner flows in circulating water channel (CWC). The standard 2nd- order central scheme together with a deferred correction meth- od was applied for the convective terms. All the other terms wrer discretized using 2nd order central differencing. The standard k-ε model was used for the approximation of turbu- lent flows. First. This method used to calculate the trubulent flows in a 90 deg. Bend and the computed results are in good a- gerements with the experiment. This method was also em- ployed to calculate the flows in a model CWC corner.
