Energy transfer, Intermittency and Mixing in Shear-Driven Stratified Turbulence
Chandra Shekhar Lohani, Vishwanath Shukla
We investigate a stably stratified flow driven by deterministic Kolmogorov forcing that generates horizontal shear, using direct numerical simulations over a broad range of stratif…
Orientation Dynamics of Gyrotactic Microswimmers in Turbulent Flows
Suraj Kumar Nayak, Vishwanath Shukla, Akshay Bhatnagar
We study the dynamics of gyrotactic microswimmers suspended in homogeneous and isotropic turbulence by using direct numerical simulations (DNS). The swimmers are characterized by t…
Nonequilibrium Continuous Transition in a Fast Rotating Turbulence
Chandra Shekhar Lohani, Suraj Kumar Nayak, Kannabiran Seshasayanan +1
We study the saturation of three-dimensional unstable perturbations on a fast rotating turbulent flow using direct numerical simulations (DNSs). Under the effect of Kolmogorov forc…
Machine learning of Ising criticality with spin-shuffling
Pallab Basu, Jyotirmoy Bhattacharya, Dileep Pavan Surya Jakka +2
We investigate the performance of neural networks in identifying critical behaviour in the 2D Ising model with next-to-nearest neighbour interactions. We train DNN and CNN based cl…
Equivalence of nonequilibrium ensembles: Two-dimensional turbulence with a dual cascade
Kannabiran Seshasayanan, Karthik Subramaniam Eswaran, Maheswar Maji +2
We examine the conjecture of equivalence of nonequilibrium ensembles for turbulent flows in two-dimensions (2D) in a dual-cascade setup. We construct a formally time-reversible Nav…
Inertial Particles in Superfluid Turbulence: Coflow and Counterflow
Sanjay Shukla, Akhilesh Kumar Verma, Vishwanath Shukla +2
We use pseudospectral direct numerical simulations (DNSs) to solve the three-dimensional (3D) Hall-Vinen-Bekharevich-Khalatnikov (HVBK) model of superfluid Helium. We then explore…
