NUMERICAL SIMULATION OF SELF-PROPELLED MOTION OF TWO ROTATING SIDE-BY-SIDE CIRCULAR CYLINDERS

Abstract

In the present work, the problem of the motion of self-propelled two rotating side-by-side circular cylinders in a viscous incompressible fluid is investigated numerically. The surface of left cylinder rotates counterclockwise and right clockwise at the same speed. The flow patterns and the drag coefficients of regimes of self-motion are analyzed for a various range of rotational speed and different gap spacings at a moderate Reynolds number.
