Interaction of a Vortex Pair with a Polymeric Fluid Layer
Rabia Sonmez, Robert A. Handler, David B. Goldstein +3
The interaction of vortical structures with boundaries has been extensively studied in Newtonian fluids, where conditions such as no slip walls, free surfaces, or contaminated surf…
Generation of Laminar Vortex Rings by an Impulsive Body Force
Rabia Sonmez, Robert A. Handler, Ryan Kelly +2
It is shown that laminar vortex rings can be generated by impulsive body forces having particular spatial and temporal characteristics. The method produces vortex rings in a fluid…
The role of the `monopole' instability in the evolution of 2D turbulent free shear layers
Saikishan Suryanarayanan, Garry Brown, Roddam Narasimha
The role of instability in the growth of a 2D, temporally evolving, `turbulent' free shear layer is analyzed using vortex-gas simulations that condense all dynamics into the kinema…
Spatially evolving vortex-gas turbulent free shear layers: Part 2. Coherent structure dynamics in vorticity and concentration fields
Saikishan Suryanarayanan, Roddam Narasimha
This paper examines the mechanisms of coherent structure interactions in spatially evolving turbulent free shear layers at different values of the velocity ratio parameter λ=$(U_1-…
Spatially evolving vortex-gas turbulent free shear layers: Part 1. Effect of velocity ratio, and upstream and downstream conditions on spread-rate
Saikishan Suryanarayanan, Roddam Narasimha
The relevance of the vortex-gas model to the large scale dynamics of temporally evolving turbulent free shear layers in an inviscid incompressible fluid has recently been establish…
The Turbulent 'Mixing' Layer as a Problem in the Non-equilibrium Statistical Mechanics of a Vortex Gas
Saikishan Suryanarayanan, Roddam Narasimha, N. D. Hari Dass
The objective of this paper is to unravel any relations that may exist between turbulent shear flows and statistical mechanics, through a detailed numerical investigation in the si…
