Abstract The pressure distribution around a cylinder at different Reynolds numbers has been measured in a water tunnel, in which temperature andfluid velocity can be controlled. These pressure distributions are compared with published h t a for d'ynamically similar flows and related to silica &position experiments around circular cylinders, which were carried out in the same water tunnel, under the same,flow conditions. Silica scale thickness varies around the cylina!er with the greatest deposition rate occurring, at least initially, in regwns of high wall shear stress. Further qeriments are planned to overcome slight flow variability apenenced with the current configuration.
