The main contribution of this paper is to develop a new methodology to include effects of
surface roughness on aerodynamic of bodies. The numerical approach simulates the …

The present work deals with two-dimensional numerical simulations to study wake structures
and flow dynamics past a circular cylinder. Based on a physical sense that roughness …

The objective of this paper is to simulate the effects of surface roughness of a ground plane
on trajectories of two-dimensional primary vortical structures shedding from wing tips of …

The purpose of this work is to present a roughness surface model to be used with the mesh
free vortex method to simulate numerically the flow past a circular cylinder. The roughness …

This numerical study is related to the determination of aerodynamic loads of a circular
cylinder near a moving ground by using a two-dimensional purely Lagrangian vortex …
