Abstract
The general approach to the application of the LS-STAG method for RANS simulation and for numerical simulation in coupled hydroelastic problems is suggested. According to the concept of the LS-STAG method normal Reynolds stress components are sampled on the base mesh (similar to pressure discretization) and shear ones are sampled in the upper right corners of the base mesh cells. Thus, for the shear Reynolds stresses an additional mesh (xy-mesh) is introduced. In this research the LS-STAG-discretization for convective and diffusive fluxes on the xy-mesh is developed. A software package is developed for numerical solution of the Navier-Stokes and Reynolds-averaged NavierStokes equations by using the LS-STAG method. To validate this approach and developed software package the flow past circular airfoil at the Reynolds numbers Re = 1000 and Re = 3900 was simulated. Some numerical results are also presented for simulation of a circular airfoil wind resonance phenomenon.
