Abstract A novel approach is proposed for the numerical evaluation of scale thickness and its distribution in a mixing tank. While a majority of the available literature on the scale build-up is focusing on the applications of chemical anti-scalants, few works have been devoted to preventing scale formation through a proper design and operation of stirred vessels. The methodology proposed in the current study consists of two major phases: 1) identifying an accelerated process to grow scales on the walls of a laboratory reactor and 2) analysing the grown scale physically. These objectives were achieved through the fabrication of a reactor that could be disassembled and scanning the reactor's surface using a coordinate measuring machine (CMM). The proposed approach was used to study the effects of liquid flow velocity and experiment duration on the pattern of the scale formed qualitatively and quantitatively.
