Pressure Gradient and Friction Factor for Sedimentation and Fluidisation of Uniform Spheres in Liquids

Abstract A new method is given for the calculation of the drag force, pressure gradient and friction factor for sedimenting suspensions and fluidised beds of uniform spherical particles in liquids. A comparison is made with previous methods of correlation. In addition, the relationship between the various drag coefficients for particles in concentrated suspensions is clarified. The importance of the particle-to-vessel diameter ratio in determining the value of the drag coefficient is established.
