DNS and Experiments of Flow Past a Wired Cylinder at Low Reynolds Number

We have performed high resolution direct numerical simulations (DNS) at Reynolds number Re=50, 160 and 500 for flow past a wired cylinder. Comparisons with companion PIV measurements made at Re=160 validate the DNS results. It is found that at Re=160 and Re=500 vortex shedding is suppressed substantially while the drag force decreases compared to a smooth cylinder flow.
