Analysis of Unsteady Separated Turbulent Flow in Asymmetric Plane Diffuser by Direct Numerical Simulation

3D Numerical Simulation of the Separated Turbulent Shallow Flow around a Single Side Obstacle

In this paper, the performance of Reynolds Averaged Navier Stokes (RANS) simulations was evaluated to predict the flow structure developed by the presence of a sidewall obstruction in a uniform open-channel shallow flow. The study of these flow structures is important because they present in several real world configurations, such as groynes in rivers, where the erosion processes, mass transpor...

Application of HPCN to Direct Numerical Simulation of Turbulent Flow

This poster shows how HPCN can be used as a pathnding tool for turbulence research. The parallelization of direct numerical simulation of turbulent ow using the data-parallel model and Fortran 95 constructs is treated, both on a shared memory and a distributed memory computer. Introduction Computer simulation has become a major tool for studying turbulent ow in many technological and environmen...

Studies of turbulent boundary layer flow through direct numerical simulation

The objective has been to study turbulent boundary layers under adverse pressure gradients (APG) through direct numerical simulation (DNS). The numerical code is based on a pseudo-spectral technique which is suitable for the simple geometry (flat plate) considered here. A large effort has been put into the optimization of the numerical code on various super computers. Five large simulations hav...
