Two general-purpose Reynolds-averaged Navier–Stokes flow solvers, OVERFLOW and BCFD, are used to analyze the NASA Common Research Model in a wing–body configuration. The codes are run on structured and unstructured common-grid families built spec

Drag predictions of the DLR-F6 wing body, with and without the FX2B fairing, are demonstrated using both structured and unstructured grid solvers. The ability to accurately predict incremental drag is key to drag-based design and optimization. The fo

The deposition of dense solid particles in a downward, fully developed turbulent square duct flow at Re τ = 360, based on the mean friction velocity and the duct width, is studied using large eddy simulations of the fluid flow. The fluid and the par

We present a new algorithm for computing binary collisions in gas particle flows. The algorithm is more efficient but less accurate than a proactive method, but more accurate than a purely retroactive method. The method is used in conjunction with a
