The present study deals with the Large-Eddy Simulation of the turbulent flow past a swept fence at low Reynolds numbers. The swept fence geometry was introduced by McCluskey et al. (1991) as a way of gathering information on the behaviour of near wall flows beneath a separation region in the presence of a significant cross-flow. The configuration avoids both the lack of generality of typical two-dimensional flows and the difficulties of fully three-dimensional flows. In the present case, Large-Eddy Simulation is both a challenging and promising approach. On the one hand, as in most low-Reynolds number and recirculating flows, simple wall models cannot be applied, Akselvoll and Moin (1997), on the other hand, due to the relatively low Reynolds of the flow and the type of scaling suggested in Hardman and Hancock (2000), accurate resolution of the near wall region can be achieved without incurring prohibitively high computational costs. Numerical data are currently been collected and compared to experimental data for use in the formulation of near wall models for LES. A low-Reynolds number variant of the dynamic SGS model of Germano et al. (1991) is also tested in this flow.
