Stretching and Lyapunov Exponents of Polymers in Ultra-Dilute Turbulent Solutions
Demosthenes Kivotides
We analyse bead--spring polymers coupled to Navier--Stokes turbulence in ultra--dilute solutions at Weissenberg number \(Wi\approx 80\). The polymers do not alter the large-scale t…
Gravitomagnetic relativistic effects on turbulence
Demosthenes Kivotides
The dynamics of fluid-matter under the influence of gravitomagnetic fields are formulated and solved for the case of fully developed turbulence. Gravitomagnetic effects reduce the…
Quantum turbulence decay
Demosthenes Kivotides
We develop a computational model of quantum turbulence decay employing a kinematic prescription for the normal fluid. We find that after an initial transient, the length of the vor…
Turbulence without inertia in quantum fluids
Demosthenes Kivotides
Numerical calculations of Helium-II hydrodynamics show that a dense tangle of superfluid vortices induces in an initially stationary normal fluid a highly dissipative, complex, vor…
Vortex Ring Reconnections
Philippe Chatelain, Demosthenes Kivotides, Anthony Leonard
We investigate numerically the Navier-Stokes dynamics of reconnecting vortex rings at small number. We find that reconnections are dissipative due to the smoothing of vorticit…
