flow profile and flow type also transited along pipeline inter thermal stations.
在加热站间管道沿线,流态和流型随着温度的变化也会发生转变。
as dirt and other collateral material collect along an interior pipeline wall, or as the pipeline wall corrodes, the flow profile for the gas flow traveling through the pipeline changes.
由于灰尘和其他相关材料沿着内部管道壁,或者由于管道壁腐蚀,气体流过管道的流量剖面改变。
in this paper not only the equation based on the conservation of energy is derived, but also the flow profile and the states of flow are analyzed.
