Numerical Bow Shock Instabilities in Inert Polyatomic Gases
G. S. Sidharth, Anubhav Dwivedi
We investigate inviscid numerical instabilities that arise in simulations of axisymmetric flow over a hypersonic sphere in an inert, calorically perfect gas at low specific heat ra…
Accelerating multigrid solver with generative super-resolution
Francisco Holguin, GS Sidharth, Gavin Portwood
The geometric multigrid algorithm is an efficient numerical method for solving a variety of elliptic partial differential equations (PDEs). The method damps errors at progressively…
Multigrid Solver With Super-Resolved Interpolation
Francisco Holguin, GS Sidharth, Gavin Portwood
The multigrid algorithm is an efficient numerical method for solving a variety of elliptic partial differential equations (PDEs). The method damps errors at progressively finer gri…
Reattachment streaks in hypersonic compression ramp flow: an input-output analysis
Anubhav Dwivedi, G. S. Sidharth, Joseph W. Nichols +2
We employ global input-output analysis to quantify amplification of exogenous disturbances in compressible boundary layer flows. Using the spatial structure of the dominant respons…
