Abstract

Measurements are reported of the resuspension of 10 and 20 micron alumina spheres and graphite particles from a polished stainless steel flat plate in fully developed turbulent channel flow. Preliminary measurements were made of the normal and tangential forces holding the particles onto the surface. Whilst both forces had a broad spread and were on average much reduced in value compared to that of smooth contact, the average tangential force was typically of order 1/100th of the normal adhesive force, suggesting as has been reported previously that drag forces play a more important role in suspending a particle than lift forces.
