摘要
应用Fluent软件,分别在匀速度和抛物线形速度分布入口条件下模拟圆管层流流场得到进出口静压降,并与理论值进行比较。结果显示了匀速度入口下进出口静压降与理论值误差百分比随雷诺数增加而急剧增大;而抛物线形速度入口下进出口压降与理论值基本吻合。
Inner laminar filed of round pipe was numerically simulated with FLUENT software to get static pressure drop by using uniform velocity and parabolic velocity distribution respectively on inlet face.Compared with the theoretical static pressure drop,the result showed that percentage error is on the increase rapidly with Reynolds number rise by using uniform velocity and the static pressure drop agrees with theoretical value by using parabolic velocity.
