Thermal convection in one, two, three and four dimensions
Ambrish Pandey, Harshit Tiwari, Katepalli R. Sreenivasan
We study by means of direct numerical simulations the influence of the dimensionality of convection on flow properties. We call attention to a few general principles from consideri…

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…
