Abstract

Few areas in fluid mechanics have received more attention than that of flow past a bluff body. In particular, flow across a circular cylinder in unconfined and confined flow is a classical problem, and has been studied experimentally, visually and numerically. Studies on flow characteristics of tubes in cross flow have long been of interest due to their wide use in engineering applications. Though the geometry is very simple, the flow pattern in the vicinity of the cylinder is full of variety. This problem has not yielded to closed form analytical solution except at very low Reynolds numbers. The large volume of literature using a variety of numerical approaches viz., finite difference, finite element and finite volume methods associated with this particular subject attests to the importance as well as the complexity of the fluid flow involving adverse pressure gradients, separation, eddy shedding, recirculation and reattachment. However, there is room for improvement in the agreement with experiments that has been obtained hitherto. A numerical solution that gives good agreement is also likely to be useful for benchmarking existing codes and new ones that may be written.
