Applicability of a Spinning Disk Apparatus for the Investigation of Particulate Fouling

Abstract

The applicability of a fluidically heated spinning disk apparatus (SDA) was tested for investigating the influence of the tangential velocity on the deposition of particulate material systems, in particular on latex particles. First, the SDA was characterized for particle fouling investigations with micro glass beads as a model system, then, a first series of tests was carried out with a real material system, a vinyl acetate/Versa 10 copolymer. Experiments were performed for a duration of 1 h and a tangential velocity up to 0.3 m s⁻¹. The fouling process was characterized by the local fouling layer thickness and the calculated local mass-based fouling resistance. A decrease in fouling resistance along the radius of the rotating disk as a function of the tangential velocity was observed.
