Spatio-temporal intermittency of the turbulent energy cascade
Tatsuya Yasuda, John Christos Vassilicos
In incompressible and periodic statistically stationary turbulence, exchanges of turbulent energy across scales and space are characterised by very intense and intermittent spatio-…
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…
Reduced energy consumption in stirred vessels by means of fractal impellers
Salur Basbug, George Papadakis, John Christos Vassilicos
Earlier studies have shown that the power consumption of an unbaffled stirred vessel decreases significantly when the regular blades are replaced by fractal ones. In this paper, 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…
Attached flow structure and streamwise energy spectra in a turbulent boundary layer
Sricharan Srinath, J. C Vassilicos, Christophe Cuvier +3
On the basis of (i) Particle Image Velocimetry data of a Turbulent Boundary Layer with large field of view and good spatial resolution and (ii) a mathematical relation between the…
