The effect of a plate installation upstream of an orifice on the pressurized flushing efficiency

The effect of a plate installation upstream an orifice was investigated as new method for improving the pressurized flushing efficiency. A with three different widths (B T ) installed at four distances (L orifice. According to results, significantly increased efficiency due wake vortices formed up maximum value 11.5 times relative what calculated experiment without same conditions. For best configuration width and its distance from outlet (i.e., L /D O = 0.7 B 0.5, D is diameter), length, width, depth cone by approximately 160, 90, 240% control under conditions, respectively. Four empirical equations based on effective dimensionless variables were developed, enabling users make predictions volume dimensions. Finally, importance each parameter in derived analyzed using sensitivity analysis method. results showed greater impact discharge than
