Numerical simulations are extensively used to investigate the motion of suspended particles
in a fluid and their influence on the dynamics of the overall flow. Contexts range from the …

The structure of the turbulent flow over a simplified automotive model, the Ahmed body (SR
Ahmed and G. Ramm, SAE Paper No. 8403001, 1984) with a 25 slanted back face, is …

Particulate flows have mainly been studied under the simplifying assumption of a one-way
coupling regime where the disperse phase does not modify the carrier fluid. A more …

The paper presents a comparative analysis of recent simulations, conducted in the
framework of a French-German collaboration on LES of Complex Flows, for the so-called …

The dynamics of neutrally buoyant particles transported by a turbulent flow is investigated for
spherical particles with radii of the order of the Kolmogorov dissipative scale or larger. The …

In order to introduce solid obstacles into flows, several different methods are used, including
volume penalization methods which prescribe appropriate boundary conditions by applying …

The interaction between a fixed solid spherical particle and stationary turbulence with zero
mean flow is investigated numerically. The object diameter, D, lies in the inertial range (D≈ …

The impact of turbulent fluctuations on the forces exerted by a fluid on a towed spherical
particle is investigated by means of high-resolution direct numerical simulations. The …

An original penalization method is applied to model the interaction of magnetically confined
plasma with limiter in the frame of a minimal transport model for ionic density and parallel …

This work extends the characteristic-based volume penalization method, originally
developed and demonstrated for compressible subsonic viscous flows in (J. Comput. Phys …
