Abstract

Matrix dissipation scheme is known to give more accurate solutions than scalar dissipation scheme. Matrix dissipation scheme was implemented in in-house developed JUMBO code (block structured vertex based finite volume RANS solver), which currently uses scalar dissipation scheme to introduce artificial viscosity. The implemented matrix dissipation scheme was tested for transonic flow over various airfoil sections. Numerical solutions obtained using matrix dissipation model were found to be more accurate than scalar dissipation model, particularly in the neighborhood of shock waves while still maintaining good convergence properties.
