Abstract

The paper describes an analysis of viscous pumps with shrouded Rayleigh-steps using compressible fluids. 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 pump proposed in this paper are compared with those of spiral groove viscous pumps which are frequently used. Consequently the viscous pump with Rayleigh-steps has greater flow rate and higher pressure difference.
