Influence of Suction and Blowing on Entrainment of Sand Particles
The influence of suction and blowing on the rate of entrainment of sand particles was studied experimentally. For the range of grain sizes (130 - 570 μm) suction always reduced sediment transport at a constant mean flow velocity, whereas the rate of transport increased with blowing. The results were compared with the theory of Martin on the stability of a particle under the influence of pore-water flow. It was found that the coefficient, C, relating the force on the particles at the surface of the bed to the pressure gradient in the bed, varied strongly with the grain size. The influence of suction and blowing on the bed shear stress was computed with a simple kinematic model and compared with the theory of Turcotte and others.
