The effect of solids concentration on self-induced turbulence

A model to predict the turbulence intensity due to the solid particles in a simple flow has been developed. The flow is one in which all the turbulence is due to the presence of the particles. The model accounts for energy input through the loss of potential energy by the solid particles and energy loss by turbulent dissipation. The predictions are compared for various solids concentrations and particle sizes. The peak turbulence intensity is seen to b3e reached faster for higher solid concentrations. The peak is also higher for higher concentrations. In all cases, a peak value of turbulent intensity is reached if the supply of particles is maintained. The case in which the supply of particles are no longer available to supply the turbulence with energy. When normalized by the peak value, the turbulence was seen to decay more rapidly for higher concentrations of solid particles in the present model. An experimental study will be conducted to compare with the current model.
