圆断面90°弯管局部水头损失的数值模拟
Numerical simulation of local water pressure loss for bend pipe of circular section at 90 degrees
摘要
Abstract
Choosing standard k -εturbulence model, the paper simulated the local head loss of bend with circular section at 90 degrees by use of fluent software when Re equal to 6000.The results showed that the turbulence model can better predict the second flow in the pipe caused by centrifugal force.The simulated sectional flow field and pressure distribution in the pipe all agreed well with the experiment results.The cof-fercient of local head loss gotten by calculation is almost consistent with the experiment data.Therefore the efficiency of the numerical simulation for local flow loss of bend was validated.关键词
