“…The selection of an appropriate erosion model which better represents the experimental results was performed by calculating the erosion (material weight loss) of a square shape specimen caused by a hitting vertical water/sand jet for some various operating parameters with four erosion models from literatures [9][10][11][12][13]. The results are then compared with the experimental erosion results of Wang et al [14] which applied a water/sand jet experimental set-up to investigate the effect of influencing parameters on the erosion rate of hard metals.…”

Abstract. Erosion occurring in equipment dealing with liquid-solid mixtures such as pipeline parts, slurry pumps, liquid-solid stirred reactors and slurry mixers in various industrial applications results in operational failure and economic costs. A slurry erosion tank test rig is designed and was built to investigate the erosion rates of materials and the influencing parameters such as flow velocity and turbulence, flow angle, solid particle concentration, particles size distribution, hardness and target material properties on the material loss and erosion profiles. In the present study, a computational fluid dynamics (CFD) tool is used to simulate the erosion rate of sample plates in the liquid-solid slurry mixture in a cylindrical tank. The predictions were made in a steady state and also transient manner, applying the flow at the room temperature and using water and sand as liquid and solid phases, respectively. The multiple reference frame method (MRF) is applied to simulate the flow behavior and liquid-solid interactions in the slurry tank test rig. The MRF method is used since it is less demanding than sliding mesh method (SM) and gives satisfactory results. The computational domain is divided into three regions: a rotational or MRF zone containing the mixer, a rotational zone (MRF) containing the erosion plates and a static zone (outer liquid zone). It is observed that changing the MRF zone diameter and height causes a very low impact on the results. The simulated results were obtained for two kinds of hard metals namely stainless steel and ST-50 under some various operating conditions and are found in good agreement with the experimental results.

Abstract:A slurry erosion tank test rig was designed and built to investigate the erosion rates of different materials and effects of the influencing parameters on material loss and erosion profiles. A CFD (computational fluid dynamics) tool is applied to study the flow impact velocity, solid concentration and particle size effects on the erosion rate of sample plates in the liquid-solid mixture in a cylindrical tank. The MRF (multiple reference frames) method is applied to model the rotating parts inside the tank. The flow behavior and liquid-solid interactions in the slurry tank test rig are simulated and the results are validated with the experimental data. It was approved that changing the height and diameter of each rotating zone (MRF zones) have a negligible effect on simulation results. It was observed that the erosion mass losses are increasing with increase in flow velocity and sand concentration. Both variations can be predicted with a logarithmic dependence of mass loss to rotational velocity and sand concentration. The increase in erosion rate by increase in particle size was also observed for three various particle size distributions.

“…Jafari et al [7] investigated the erosion rate numerically in a horizontal pipeline carrying a gas-solid two-phase flow using a four-way coupled EulerianLagrangian approach. They implemented the Huang et al [15] erosion model, which is a new phenomenological model for the rate of erosion that includes the properties of abrasive particles and surface material. In particular, they included the important effect of particle size, density and hardness, as well as the strength of surface material.…”

“…The discrete random walk model is used for evaluating the instantaneous turbulence fluctuating velocities. Using the detailed simulation of the gas-solid flows, the particle impingement angles and impact velocities are evaluated directly and used in the Huang et al [15] comprehensive model to evaluate the erosion rate. The resulting erosion rates are compared with those available in the literature, and the effect of various parameters are discussed.…”
