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…
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…
