Validation of an OpenFOAM®-based solver for the Euler equations with benchmarks for mesoscale atmospheric modeling

Within OpenFOAM, we develop a pressure-based solver for the Euler equations written in conservative form using density, momentum, and total energy as variables. Under simplifying assumptions, these are used to describe non-hydrostatic atmospheric flow. For stabilization of capture sub-grid processes, consider two Large Eddy Simulation models: classical Smagorinsky model one equation eddy-viscosity model. To achieve high computational efficiency, our uses splitting scheme that decouples computation each variable. The numerical results obtained with validated against data available literature benchmarks: rising thermal bubble density current. Through qualitative quantitative comparisons, show approach is accurate. This paper meant lay foundation new open-source package specifically created quick assessment approaches simulation flows at mesoscale level.
