宾汉浆液在管路中输送时的阻力

Study on the Friction of Conveying Bingham Fluid in Pipe

本文讨论了官厅浆液在管路中输送时的阻力试验结果.根据宾汉流体在管路中作层流运动时的基本方程,得出了阻力系数的精确解.由本公式求得的精确解与实测的阻力系数吻合良好,显著优于目前常用的近似解.

Results of experiments on the friction loss of conveying Bingham fluid in closed pipe are analysed in this paper. According to the basic equation for Bingham fluid transported as Laminar flow in pipe, a formula for calcu- lating theoretical friction factor is obtained. Comparison shows that the friction factor obtained from the formula keeps good agreement with the measured one.
