宾汉液体和幂律液体偏心环空层流螺旋流的流量与压降计算

THE CALCULATION OF FLOW RATE AND PRESSURE DROP FOR THE LAMINAL HELICAL FLOW OF BINGHAM FLUID AND POWER LAW FLUID IN AN ECCENTRIC ANNULAR SPACE

研究了一类带屈服应力的宾汉液体和一类不带屈服应力的幂律液体在偏心环空中的层流螺旋流的流动规律。作者过去建立了偏心环空螺旋流流场的无限细分法,并给出了视粘度分布和速度分布。在此基础上,本文在理论上,又给出了偏心环空层流螺旋流的流量和压降计算方法。

The law of the flow for the laminal helical flow of Bingham fluids with yield stress and power law fluids without yield stress was studied theoretically. The infinite subdivision method for the helical flow of the eccentric annular space in [1] was established, moreover, the apparent viscosity distribution and the velocity distribution are derived. The calculation method of the flow rate and the pressure drop are established in the study too.
