Generalized space-time fractional dynamics in networks and lattices
Thomas M. Michelitsch, Alejandro Perez Riascos, Bernard Collet +2
We analyze generalized space-time fractional motions on undirected networks and lattices. The continuous-time random walk (CTRW) approach of Montroll and Weiss is employed to subor…
Wake Characterisation of 3-Dimensional Multiscale Porous Obstacles
Jacob H. Marlow, Franck C. G. A. Nicolleau, Wernher Brevis
In this research article we study the wake formation behind 3-Dimensional Multi-scale Porous Obstacles (3DMPOs). Particle Imaging Velocimetry (PIV) is used in a non-shallow ($B/h =…
Lattice Boltzmann Method simulations of high Reynolds number flows past porous obstacles
N. M. Sangtani Lakhwani, F. C. G. A Nicolleau, W. Brevis
Lattice Boltzmann Method (LBM) simulations for turbulent flows over a fractal and non-fractal obstacles are presented. The wake hydrodynamics are compared and discussed in terms of…
PIV of swirling flow in a conical pipe with vibrating wall
Yan Xu, Yan-yue Zhang, F. C. G. A. Nicolleau +1
Swirling flows in conical pipe can be found in a number of industrial processes, such as hydrocylone, separator and rotating machinery. It has been found that wall oscillations can…
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…
