USE OF ELECTROCHEMICAL TECHNIQUES TO STUDY MASS TRANSFER RATES AND LOCAL SKIN FRICTION TO A SPHERE IN A DUMPED BED

Electrochemical techniques are developed to study the details of the flow around a single particle in a packed bed. Initial work has been done with a dumped bed of 1 in. spheres. Results are presented on the variation of the mass transfer coefficient and the shear stress around the surface of one of the spheres, the overall mass transfer rates to a sphere in a bed of inert spheres, and the effect of Reynolds number on the local mass transfer coefficient and the shear stress.
