Thermal convection in 1, 2, 3 and 4 dimensions
Ambrish Pandey, Harshit Tiwari, Katepalli R. Sreenivasan
The authors use direct numerical simulations to investigate how the dimensionality of thermal convection (from 1D to 4D) influences flow characteristics, focusing on the time neede…
Scaling in Supersonic Turbulence: Energy Spectra and Fluxes using High-Fidelity Direct Numerical Simulations
Harshit Tiwari, Dhananjay Singh, Mahendra K. Verma +1
Supersonic turbulence is vital to astrophysical and high-speed engineering flows, yet its energy transfer mechanisms remain poorly understood. We present high-resolution ()…
Hydrodynamic capture and release of a microswimmer by a meniscus corner
Subhasish Guchhait, Harshita Tiwari, Sumesh P. Thampi +1
Biological microswimmers alter their motility in complex corner geometries, facilitating their survival. However, the dynamical features of low-Reynolds-number swimming at corners…
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…
