The complexity of problem of fluid flow and heat transfer over an array of circular cylinders is quite common in industrial applications of fluid dynamics. The complex nature of the problem encountered in industry gives rise to certain significant dimensions in fluid dynamics theory. Some of them are fluid flow interaction, phase change phenomenon, interferences in flow and vortex dynamics which are typically found in compact heat exchangers, cooling of electronics equipment, nuclear reactor fuel rods, cooling towers, chimney stacks, offshore structures, hot-wire anemometry and flow control.
