I am trying to solve one fluid-structure interaction problem, where one rigid plate (maroon color) merged in fluid, and the plate should vibrate from the right end with angular velocity given in the attached figure. Sep 23, 2021 · The mechanical output power is given by P_o = T_r \omega_r, where T_r is the torque on the rotor and \omega_r is the angular velocity. Assume the positive direction is counterclockwise. velocity and pressure fields that occur in the annular gap between two concentric cylinders with a stationary outer cylinder and a rotating inner cylinder is presented. In other words, an object with uniform velo Average velocity is the result of dividing the distance an object travels by the time it takes to travel that far. z-axis, the velocity . 2000 rad/s or 3000 rad/s, the ring deforms and goes to the another degenerate mode.
