Coupling Between Thermal Oscillations in the Surface of a Micro-Cylinder and Vortex Shedding [PDF]

open access: yes, 2007
his article studies the coupling between prescribed thermal oscillations in the surface of a micro-cylinder and vortex shedding. We deal with the unsteady, laminar, compressible flow regime where the aerodynamics forces have a periodic behavior.

Numerical simulation of the transient aerodynamic phenomena induced by passing manoeuvres [PDF]

open access: yesJournal of Wind Engineering and Industrial Aerodynamics, 2013, volume 114, pages 62-71, 2015
Several three-dimensional Unsteady Reynolds-Averaged Navier-Stokes (URANS) simulations of the passing generic vehicles (Ahmed bodies) are presented. The relative motion of vehicles was obtained using a combination of deforming and sliding computational grids.
