Numerical Simulation of Dynamic Fluid-Structure Interaction with Elastic Structure–Rigid Obstacle Contact

An implicit scheme by partitioned procedures is proposed to solve a dynamic fluid–structure interaction problem in the case when structure displacements are limited rigid obstacle. For fluid equations (Sokes or Navier–Stokes), fictitious domain method with penalization was used. The equality of and velocities at interface obtained using technique. surface forces were computed solution domain. A quadratic optimization linear inequalities constraints solved obtain displacements. Numerical results presented.
