Power Consumption of a Fluid-Loaded Hinged Scraper Blade

Abstract

Normal and shear forces on a fluid-loaded hinged scraper blade were calculated by the stream function shown in the previous reports. Power consumption of the blade was obtained theoretically on the basis of the equilibrium condition of those forces.
When the scraper angle, or the number or the width of the blades was changed, the theoretical power consumption of the blade was compared with the experimental results and agreed fairly well with them.
