Název v původním jazyce

An immersed boundary method for flow simulations around stationary and moving rigid particles

Popis výsledku v původním jazyce

In this contribution we propose hydrodynamics simulations of incompressible viscous flow around rigid particles. The hydro-dynamical interactions between moving bodies and fluid were calculated by using multi-direct forcing scheme and the immersed boundary method. In this way, fixed uniform Cartesian mesh can be used and the no-slip boundary conditions are well satisfied. Spatial discretization of the immersed boundary formulation is based on a fixed Cartesian mesh for the Eulerian variables, and a moving curvilinear mesh for Lagrangian variables. The two types of variables are linked by interaction equations that involve a smoothed approximation to the Dirac delta function. The main aim of this work was study of the particles motions and interactionsby the evaluation of particles positions, velocities and accelerations. It was shown that immersed boundary method is able to successfully describe interactions between particle and fluid, the interactions between particle and particle an
