Vertical motions of heavy inertial particles smaller than the smallest scale of the turbulence in strongly stratified turbulence
F. C. G. A. Nicolleau, K. -S. Sung, J. C. Vassilicos
We study the statistics of the vertical motion of inertial particles in strongly stratified turbulence. We use Kinematic Simulation (KS) and Rapid Distortion Theory (RDT) to study…
On recurrence of random walks with long-range steps generated by fractional Laplacian matrices on regular networks and simple cubic lattices
T. M. Michelitsch, B. A. Collet, A. P. Riascos +2
We analyze a random walk strategy on undirected regular networks involving power matrix functions of the type where indicates a `simple' Laplacian matrix. We re…
Non-equilibrium evaporation/condensation model
B. V. Librovitch, A. F. Nowakowski, F. C. G. A. Nicolleau +1
A new mathematical model for non-equilibrium evaporation/condensation including boiling effect is proposed. A simplified differential-algebraic system of equations is obtained. A c…
Return to axi-symmetry for pipe flows generated after a fractal orifice
F. C. G. A. Nicolleau
We present experimental results obtained from pipe flows generated by fractal shaped orifices or openings. We compare different fractal orifices and their efficiencies to re-genera…
Passage of a shock wave through inhomogeneous media and its impact on a gas bubble deformation
A. F. Nowakowski, A. Ballil, F. C. G. A Nicolleau
The paper investigates shock-induced vortical flows within inhomogeneous media of nonuniform thermodynamic properties. Numerical simulations are performed using an Eularian type ma…
Effect of gravity on clustering patterns and inertial particle attractors in Kinematic Simulation
M. Farhan, F. C. G. A. Nicolleau, A. F. Nowakowski
In this paper, we study the clustering of inertial particles using a periodic kinematic simulation. The systematic Lagrangian tracking of particles makes it possible to identify th…
Wavelet analysis of Wave motion
F. C. G. A. Nicolleau, J. C. Vassilicos
In this paper high resolution wave probe records are examined using wavelet techniques with a view to determining the sources and relative contributions of capillary wave energy al…
Effect of energy spectrum law on clustering patterns for inertial particles subjected to gravity in Kinematic Simulation
F. C. G. A. Nicolleau, M. Farhan, A. F. Nowakowski
We study the clustering of inertial particles using a periodic kinematic simulation. Particles clustering is observed for different pairs of Stokes number and Froude number and dif…
