Conservative regularization of neutral fluids and plasmas
Sonakshi Sachdev
Ideal systems of equations such as Euler and MHD may develop singular structures like shocks, vortex/current sheets. Among these, vortical singularities arise due to vortex stretch…

Nonlinear dispersive regularization of inviscid gas dynamics
Govind S Krishnaswami, Sachin Phatak, Sonakshi Sachdev +1
Ideal gas dynamics can develop shock-like singularities with discontinuous density. Viscosity typically regularizes such singularities and leads to a shock structure. On the other…
