The Kanazawa Theatre), Kanazawa, Ishikawa, Japan, A large-eddy simulation analysis solver using the multi-block grid with several block interface conditions is developed. The governing equations are the three-dimensional compressible Navier-Stokes equations in the generalized curvilinear coordinates. We adopt a sixth-order compact finite difference scheme for the convective and viscous terms and a fourth-order Runge-Kutta method for time integration. We introduce a block interface condition (BIC) that is newly developed and constructed based on the analogy between the finite volume scheme and the finite difference scheme. The BIC is compared with a characteristic based interface condition (CIC). We consider a single vortex convection crossing the boundary interface between the uniform Cartesian grid and the uniform Cartesian grid with considerable tilt as a test problem. Effects of strength of the vortex on the pressure distribution of the moving vortex are studied. A comparison of the pressure distribution of the vortex at the boundary interface presents that in the case of strong vortex the results of BIC are comparable to those of the CIC while in the case of weak vortex numerical oscillations are observed when the vortex crosses the interface. Furthermore, results obtained using the CIC and the BIC are considerably improved with increasing grid resolution in normal to the block interface., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1630031005, レポート番号: JAXA-SP-16-007},
