Summary on Grant Application Form
The proposed research will determine the extent to which turbulent dispersion of particles leads to inter-particle collisions and evaluate and improve the ability of engineering computational models to predict it. The measurements will quantify the probability of particle collisions and fluid-particle velocity correlations, in the appropriate Lagrangian frame of reference, as a function of injection location and time after injection of particle pairs and correlate these quantities with gecmetry of fluid and inertial particle trajectories and lengthscale of the fluid flow. Particle response to the fluid flow and gravitational effects will be varied and will be characterised in terms of non-dimensional numbers, including particle Stokes number and drift parameter. The experimental results will provide new understanding of the influence of turbulent flow structure on particle dispersion and collision rate. Numerical calculations, based on a k-e model for the continuous flow and Lagrangian tracking for the dispersed phase, will evaluate the ability of models to predict inter-particle collisions, identify model limitations and provide suggestions for improvements. The evaluation of the computational models will be extended through cooperation with the group of Dr. Vassilicos in Cambridge, which will evaluate and develop new computational approaches for particle dispersion incorporating detailed fluid flow structures.
