Similarity and Dimensional Methods in Mechanics

The discretization of Navier-Stokes equations on mixed unstructured grids is discussed. Because mixed grids consist of different cell types, the question arises as to how the discretization should treat these cell types in order to result in a stable and accurate solution method. This issue is addressed in relation to the discretization of inviscid and viscous fluxes. The discretization of the inviscid fluxes is carried out with both a centered and an upwind scheme. For the centered scheme, problems exist on mixed grids with the damping properties of the fourth-difference operator. The problems with the fourth-difference operator are investigated for two stencils by both truncation error and Fourier analysis. It is shown that one form exhibits superior damping for high frequencies, which is corroborated using numerical experiments. For the upwind scheme, a commonly used gradient-reconstruction method based on the Green-Gauss theorem does not show satisfactory behavior on mixed grids. Another gradient reconstruction method based on a Taylor series expansion previously derived in two dimensions is extended to three dimensions. This method is more accurate on mixed grids but requires more storage

Design of packed bed thermal energy storage systems for high-temperature industrial process heat

A solution method for compressible turbulent flows on unstructured grids in two dimensions is described. The method can be used on grids consisting of triangular and/or quadrilateral cells. Control volumes are constructed from dual cells, and the solution variables are stored at the vertices of the grid. Grid-transparent algorithms are developed that do not require knowledge of cell types, leading to simple discretization schemes on mixed grids. The inviscid fluxes are computed from limited high-resolution schemes originally developed for unstructured triangular grids. They are easily applied to quadrilateral or mixed grids and are grid transparent. The discretization of the viscous fluxes is studied in detail. A positive, grid-transparent discretization of Laplace's equation is developed. The existence of tangential derivatives in the viscous terms prevents grid transparency. By neglecting tangential derivatives, an approximate form of the viscous fluxes is developed, which recovers grid transparency. The approximate form is shown to be similar to the thin-shear-layer approximation. Results are obtained for a transonic inviscid flow, a laminar separated flow, and a transonic turbulent flow
