Abstract

In this paper, we formulate a high-order flux correction method for three-dimensional laminar and turbulent flows on strand grids. Building on previous work, we treat flux derivatives along strands with high-order summation-by-parts operators and penalty-based boundary conditions. Where turbulence modeling is required, a robust version of the Spalart–Allmaras model is employed that accommodates negative values of the turbulence working variable. Fundamental verification and validation studies are considered, which demonstrate the flux correction method achieves high-order accuracy for both laminar and turbulent flows. The high-order flux correction requires only 30 % more walltime to converge when compared to a second-order scheme.
