| Abstract: | The fluctuating relative motion of two solid particles or liquid drops in a turbulent gas flow is analysed, yielding an expression for collision rate as a function of the particle concentration and relaxation times and the turbulence intensity and scale. Unlike earlier theories, particles of intermediate size are included, having approach velocities neither well-correlated nor completely independent. |
