Taylor vortices generated between eccentric and/or concentric rotating cylinders were investigated by experiments and also by three-dimensional incompressible Navier-Stokes simulation. The focus of the research is applied on the control of Taylor vortex cells by the jet injection from the outer cylinder wall. In the present case, 6 stable Taylor vortex cells can be controlled and the number of cells decreased to 4, so that the driving torque applied on the inner cylinder can be reduced dramatically. Furthermore, unsteady behavior of the vortex cells was discussed. These experimental results as well as obtained unsteady flow fields agreed well with those of the numerical results, so that control and reduction of Taylor vortex cells expected by numerical analyses were confirmed in the experiment
