| Description: | [DMS Seminar] Dr. Arnab Roy (Institut Elie Cartan de Lorraine (IECL), SPHINX, INRIA-NANCY, FRANCE) -- Stabilization of a rigid body moving in a compressible viscous fluid |
| Date: | Tuesday, Oct 15, 2019 |
| Time: | 3 p.m. - 4 p.m. |
| Venue: | 102, A P C Ray |
| Details: | In this talk, we discuss the stabilizability of a fluid-structure interaction system of a viscous, compressible fluid and rigid ball in a three dimension space with an external force acting on the ball produced by a spring and a damper connecting the centre of the ball to a fixed point $h_1$. We prove global-in-time existence result for this model under the condition that the initial velocities are small and the center of mass of the body is sufficiently near to $h_1$. In this scenario, we discuss the asymptotic behaviour of the whole system. |
