Dissipation of nonlinear acoustic waves in thermoviscous pores
Krishna Sahithi, Prateek Gupta
We derive a nonlinear acoustic wave propagation model for analysing the thermoviscous dissipation in narrow pores with wavy walls. As the nonlinear waves propagate in the thermovis…

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…
