摘要
对水平钢管和有机玻璃管内油水两相流动摩擦压降的变化进行了研究 ,当含水率为18%～ 10 0 %、折算液速为 0 .6～ 2 .4m /s时 ,水平管内油水两相流的摩擦压降受含水率的影响很大 ,在同一流动条件下 ,当含水率较小时 ,有机玻璃管内流体的摩擦压降大于钢管内流体的摩擦压降 ,随着含水率的增大 ,钢管内流体的摩擦压降又大于有机玻璃管内流体的摩擦压降。这说明 ,在一定条件下 ,影响油水两相流动摩擦压降的原因 ,除了粗糙度以外 。
The frictional pressure drop of oil-water two-phase flow in a horizontal steel pipe and in a Plexiglas pipe is compared and investigated. Measurements are made for superficial velocity of water varying from0.6 to 2.4m/s and input water volume fraction from 18% to 100%. It is found that water volume fractioninfluences the frictional pressure drop greatly, and under the same conditions, the frictional pressure drop in the Plexiglas pipe is greater than that in the steel pipe during small water volume fraction. With water volume fraction increasing, the latter is greater than the former. It indicates that the wettability character-istics of the pipe materials are also responsible for this disparity besides the wall roughness.
