非圧縮性流体を用いたステップ形ビスコス・ポンプの特性 : 理論解析

The paper describes an analysis of viscous pumps with shrouded pockets using incompressible fluids. It was found that there is a linear relation between the flow rate and the discharge pressure. The optimum pump geometry for the maximum flow rate is presented. Frictional torque is examined for the optimized pump geometry. Finally, the characteristics of the pumps proposed in this paper are compared with those of spiral groove viscous pumps which are frequently used.
