A Wave Appropriate Discontinuity Sensor Approach for Compressible Flows
Amareshwara Sainadh Chamarthi, Natan Hoffmann, Steven Frankel
In this work, we propose a novel selective discontinuity sensor approach for numerical simulations of the compressible Navier-Stokes equations. Since transformation to characterist…
On the Application of Gradient Based Reconstruction for Flow Simulations on Generalized Curvilinear and Dynamic Mesh Domains
Hemanth Chandravamsi, Amareshwara Sainadh Chamarthi, Natan Hoffmann +1
Accurate high-speed flow simulations of practical interest require numerical methods with high-resolution properties. In this paper, we present an extension and demonstration of th…
On the role of spectral properties of viscous flux discretization for flow simulations on marginally resolved grids
Amareshwara Sainadh Chamarthi, Hemanth Chandra Vamsi K, Natan Hoffmann +2
In this note, the importance of spectral properties of viscous flux discretization in solving compressible Navier-Stokes equations for turbulent flow simulations is discussed. We s…
Impact of wall modeling on kinetic energy stability for the compressible Navier-Stokes equations
Vikram Singh, Steven Frankel, Jan Nordström
Affordable, high order simulations of turbulent flows on unstructured grids for very high Reynolds number flows require wall models for efficiency. However, different wall models h…
