柱状粒子在流场中受力状况的实验研究

An Experimental Study of the Force and Torque on Cylindrical Particle in Simple Fluid

柱状粒子悬浮流在自然界和工业生产过程中十分普遍 ,但对其的研究则还处在初期阶段。本文对柱状粒子在层流中的受力状况进行了实验研究 ,得到了柱状粒子在层流中受到的阻力、升力和力矩随粒子长径比和方位角变化的经验公式 。

Cylindrical particle suspensions are common in both nature and industry,but its reports are few.An experimental study of the force and torque operating on the cylindrical particle in simple fluid carries out,and obtains three empirical formulas for the force and torque,provides bases for further research on the motion property of the cylindrical particle suspension.
