This paper describes a study of the erosion of a polymer-particle coating system by a water jet apparatus. Modified versions of two established wear models were applied to this system; these were based on a simple hardness controlled abrasion model and a bulk toughness controlled abrasion model. The mechanical properties of the coatings were modified and their bulk properties were characterized using...
The fouling of surfaces during the manufacture of liquid products is a serious problem for the foods industry. However, it also affects many other production processes such as paint manufacture and the production of detergents, the latter being of primary interest for this work. The use of cleaning chemicals to remove soil layers is considered highly undesirable. Not only does the disposal of the...
This paper describes a preliminary study of the mechanisms of the removal of surface coatings in hydrodynamic flows. The bulk cohesive and interfacial properties of model deposits were measured and experiments under liquid flows were also performed to investigate the effects of hydrodynamic stresses on the deposits. Comparisons were made between the erosion characteristics of deposits under hydrodynamic...
