The investigation of turbulent statistics of a fibre suspension undergoing mixing

grantor: University of TorontoThis thesis investigates the statistical properties of a fibre suspension in a turbulent flow. An experiment in a mixing jar was performed using Particle Image Velocimetry (PIV) optimized with particle tracking and refractive index matching. The experimental Reynolds numbers range from 13,300 to 53,400 (Re = 'NR'2/[nu], where N is the rotation speed of the impeller in that tank, R is the radius of the impeller which is 0.0125m, [nu] is the kinetic viscosity which is 15.6 x10-6 m 2/'s'). The effect of various mass concentrations of fibres on the flow properties were investigated and the flow patterns in the mixing tank were analyzed. Turbulence quantities were strongly influenced by the existence of the fibres in the liquid.M.A.Sc
