Scalar mixing in non-Markovian homogeneous isotropic synthetic turbulence
Pratyush S. Awasthi, Joaquim P. Jossy, Amitabh Bhattacharya +1
We show that non-Markovianity of the velocity field is an essential property of turbulent mixing. We demonstrate this via passive scalar mixing by synthetically generated stochasti…
Active Scalar Mixing by Homogeneous Isotropic Turbulence
Joaquim P. Jossy, Pratyush S. Awasthi, Prateek Gupta
We study the mixing of active scalars by homogeneous isotropic incompressible stochastic velocity fields. We consider both Navier-Stokes generated turbulent fields as well as artif…
Role of phase distortion in nonlinear saturation of the unstable acoustic modes in hypersonic parallel flow boundary layer
Altaf Ahmed, Joaquim P. Jossy, Prateek Gupta
We analyze the role of the relative phasing in the nonlinear saturation of the unstable Mack modes in a hypersonic parallel flow boundary layer in two dimensions (2D). As the linea…
Mixing of active scalars due to random shock waves in two dimensions
Joaquim P. Jossy, Prateek Gupta
In this work, we investigate the mixing of active scalars in two dimensions by the stirring action of stochastically generated shock waves. We use direct numerical simulations (DNS…
Baroclinic interaction of forced shock waves with random thermal gradients
Joaquim P. Jossy, Prateek Gupta
Density gradients aligned at an angle to pressure gradients result in baroclinic torque in fluid flows, generating vorticity. In this work, we study the vorticity generated by the…
