Abstract
The pressure distribution around a cylinder at different Reynolds numbers has been measured in a water tunnel, in which temperature and fluid velocity can be controlled. These pressure distributions are compared with published data for dynamically similar flows and related to silica deposition experiments around circular cylinders, which were carried out in the same water tunnel, under the same flow conditions. Silica scale thickness varies around the cylinder with the greatest deposition rate occurring, at least initially, in regions of high wall shear stress. Further experiments are planned to overcome slight flow variability experienced with the current configuration.
