Solid Particle Erosion on Different Metallic Materials

Numerical Investigation of the Influence of Sand Particle Concentration on Long Radius Elbow Erosion for Liquid-Solid Flow

Erosion caused by sand transportation in flow changing devices is a serious concern in the hydrocarbon and mineral processing industry, which entail to failure and malfunction of flow devices. In this study, computational fluid dynamics (CFD) with discrete phase models (DPM) were employed for analysis of carbon steel long radius 90-Degree elbow erosion due to the sand concentration of 2, 5 and ...

Solid Particle Erosion of Thermal Sprayed Coatings

Solid particle erosion is an important material degradation mechanism. Although various methods of coating are tried and used for protection against erosion, thermal sprayed coating for such purpose is the most widely used method. In this chapter, evolution of thermal sprayed coating, erosion testing methods, and erosive wear of thermal sprayed coatings are discussed extensively with emphasis o...

Hardness is the most SOLID-particle erosion is a loss of material during repetwidely used property to correlate with the erosion rates of itive impacts of solid particles and is one of the primary materials. For pure metals, some correlation between erosion reasons for fly ash–borne damage of power generation comrate and hardness has been shown.[4] However, se...
