Shear-banding instability in arbitrarily inelastic granular shear flows
Priyanka Shukla, Lima Biswas, Vinay Kumar Gupta
One prototypical instability in granular flows is the shear-banding instability, in which a uniform granular shear flow breaks into alternating bands of dense and dilute clusters o…

Moment theories for a d-dimensional dilute granular gas of Maxwell molecules
Vinay Kumar Gupta
Various systems of moment equations---consisting of up to (d+3)(d^2+6d+2)/6 moments---in a general dimension d for a dilute granular gas composed of Maxwell molecules are derived f…

Coupled constitutive relations: a second law based higher order closure for hydrodynamics
Anirudh Singh Rana, Vinay Kumar Gupta, Henning Struchtrup
In the classical framework, the Navier-Stokes-Fourier equations are obtained through the linear uncoupled thermodynamic force-flux relations which guarantee the non-negativity of t…
