Direct numerical simulation of flow across a compliant cylinder
نویسندگان
چکیده
A direct numerical simulation (DNS) code is constructed for solving flow across a three-dimensional deformable bluff body. In the present study, DNS of flow across rigid and compliant cylinders is performed to evaluate the code and the drag reduction effect with a compliant coating. The Strouhal number of shedding of the Karman vortex is calculated and it agrees well with that reported in the literature. Additionally, a slight increase of pressure drag is observed while the friction drag is reduced.

The method of lattice boltzmann equation(LBE) is a kinetic-based approach for fluid flow computations. In the last decade, minimal kinetic models, and primarily the LBE, have met with significant success in the simulation of complex hydrodynamic phenomena, ranging from slow flows in grossly irregular geometries to fully developed turbulence, to flow with dynamic phase transitions.
