Abstract

Several ways of achieving higher order accuracy on arbitrary grids are explored. These include polynomial reconstructions based on point and cell average values and the Discontinuous Galerkin method, in which the solution is expanded within a cell, and evolution equations are derived for the expansion coefficients. The polynomial reconstruction scheme based on cell averages is also extended to deal with unsteady viscous flows to higher order accuracy.
