The Effect of Rotation Rate Parameter on Two Circular Cylinders in Steady and Unsteady Regimes at Different Reynolds Numbers
The effect of rotation rate parameter, cylinder diameter, and the variation of Reynolds number on the circular cylinder was the main object of this 2D numerical study. Rotating and stationary circular cylinder in steady and unsteady incompressible flow has been analysed. For each value of Reynolds n...

| description | The effect of rotation rate parameter, cylinder diameter, and the variation of Reynolds number on the circular cylinder was the main object of this 2D numerical study. Rotating and stationary circular cylinder in steady and unsteady incompressible flow has been analysed. For each value of Reynolds number, we have varied the rotation rate parameter clockwise and anti-clockwise to visualize their effect on the drag, lift, and coefficients. All cases have carried out steady laminar, unsteady laminar, and turbulent regimes. A realizable K-epsilon model has been used to solve the Navier Stokes equations for the turbulent regime. Results were in good agreement with the recent findings. |
