Mathematical formulation of mode-to-mode energy transfers and energy fluxes in compressible turbulence
Dhananjay Singh, Harshit Tiwari, Lekha Sharma +1
Understanding compressible turbulence is critical for modeling atmospheric, astrophysical, and engineering flows. However, compressible turbulence poses a more significant challeng…

Classical 1/3 Nusselt number scaling in highly turbulent compressible convection
Harshit Tiwari, Mahendra K. Verma
Planetary and stellar convection, which are compressible and turbulent, remain poorly understood. In this paper, we report numerical results on the scaling of Nusselt number ($\mat…

Compressible turbulent convection at very high Rayleigh numbers
Harshit Tiwari, Lekha Sharma, Mahendra K. Verma
Heat transport in highly turbulent convection is not well understood. In this paper, we simulate compressible convection in a box of aspect ratio 4 using computationally-efficient…
