内容記述 | A spectral volume (SV) method for unstructured grids, recently proposed by Wang, et al., is developed for solving the hyperbolic conservation law. In SV method, a higher order reconstruction of dependent variable is available without referring to neighboring cells. The resulting scheme is very compact, and is suitable for unstructured mesh method. In this study, linear advective equations are first solved for two- and three-dimensional computational domain. From the computed results, the spatial accuracy of the present SV scheme is directly examined. It is shown that a second order of spatial accuracy is favorably achieved. However, for the third order case, the obtained accuracy of the present SV scheme becomes generally less than third order, and it shows some dependence on the mesh systems as well as on the wave propagation direction. A preliminary calculation of inviscid flowfield over RAE2822 wing section is made. The computed pressure profile agrees well with that of the experimental data, though the shock location is positioned downstream side because of the absence of viscous effect. | |||||
