Effects of free-slip boundary conditions on the flow around a curved circular cylinder
Free-slip boundary conditions are routinely used in simulations of bluff body wakes without spanwise homogeneity. The impact of the free-slip condition on the wake behind a curved cylinder is considered. Inclusion of a six diameter long straight extension turned out to be sufficient to separate the adverse impact of free-slip from the curvature effects. (C) 2013 Elsevier Ltd. All rights reserved.
