Two Dimensional Flow between Eccentric Rotating Cylinders

抄録

This study is concerned with the flow of a viscous incompressible fluid between eccentric cylinders which rotate with respective angular velocities. The flow pattern between cylinders, and the torque and flow force exerted on each cylinder are discussed for a wide range of radius ratios and eccentricities. The revolutionary motion of the rotating inner cylinder around the center of the stationary outer cylinder is also discussed. The analysis is based both on the Stokes approximation and on the numerical solution of the Navier-Stokes equations. The flow patterns obtained from the analysis are compared with experimental results.
