2D Numerical simulations of wake behind cylinder using spectral element method
Pech, Jan
We investigated 2D numerical simulation of wake in the flow behind circular cylinder. The main object of observance was the frequency of vortex shedding (Strouhal number (St)) depending on the Reynolds number (Re). Using spectral element method we performed a set of simulations to check the onset of vortex shedding, e.g. the critical Reynolds number and relation St-Re. Model of wake behind heated cylinder was computed using commercial software.
