Dynamics of an internally actuated elastic particle in a plane Poiseuille flow
Shashikant Verma, Prateek Anand, Navaneeth Kizhakke Marath
We analytically analyse the dynamics of an internally actuated particle, modelled as a compressible elastic sphere embedded with a magnetic bead at its undeformed centre, translati…
The dynamics of thermalisation in the Galerkin-truncated, three-dimensional Euler equation
Rajarshi, Mohammad Saif Khan, Prateek Anand +1
The inviscid, partial differential equations of hydrodynamics when projected via a Galerkin-truncation on a finite-dimensional subspace spanning wavenumbers $-{\bf K}_{\rm G} \le {…
Inertial migration of slender prolate and thin oblate spheroids in plane Poiseuille flow
Prateek Anand, Ganesh Subramanian
We theoretically examine the inertial migration of a neutrally buoyant spheroid of aspect ratio in wall-bounded plane Poiseuille flow at small particle Reynolds number ()…
Pair statistics of oblate spheroids settling in a turbulent flow
Prateek Anand, Samriddhi Sankar Ray
We perform direct numerical simulations of sub-Kolmogorov, inertial spheroids settling under gravity in homogeneous, isotropic turbulence and find that small-scale clustering, meas…
Inertial migration of a sphere in plane Couette flow
Prateek Anand, Ganesh Subramanian
We study the inertial migration of a torque-free neutrally buoyant sphere in wall-bounded plane Couette flow over a wide range of channel Reynolds numbers, , in the limit of…
