Predicting vortex merging and ensuing turbulence characteristics in shear layers from initial conditions
Anirban Guha, Mona Rahmani
Unstable shear layers in environmental and industrial flows roll up into a series of vortices, which often form complex nonlinear merging patterns like pairs and triplets. These pa…
The motion of buoyant point vortices
Jeff Carpenter, Anirban Guha
A general formulation is presented for studying the motion of buoyant vortices in a homogeneous ambient fluid. It extends the well-known Hamiltonian framework for interacting homog…
On the opposing roles of the Boussinesq and non-Boussinesq baroclinic torques in surface gravity wave propagation
Eyal Heifetz, Ron Maor, Anirban Guha
Here we suggest an alternative understanding of the surface gravity wave propagation mechanism based on the baroclinic torque, which operates to translate the interfacial vorticity…
Similarities between the structure functions of thermal convection and hydrodynamic turbulence
Shashwat Bhattacharya, Shubhadeep Sadhukhan, Anirban Guha +1
In this paper, we analyze the scaling of velocity structure functions of turbulent thermal convection. Using high-resolution numerical simulations, we show that the structure funct…
On the normal form of synchronization and resonance between vorticity waves in shear flow instability
Eyal Heifetz, Anirban Guha
A central mechanism of linearised two dimensional shear instability can be described in terms of a nonlinear, action-at-a-distance, phase-locking resonance between two vorticity wa…
