In this webinar, we discuss erosion modeling and erosion mesh deformation capabilities in ANSYS Fluent. Material erosion under a sand–liquid flow is a serious problem in many engineering applications, especially oil and gas. The ability to predict the progress of erosion in pipelines is critical. The erosion process is complex and often depends on many factors, such as fluid parameters, particle parameters, impact parameters and material parameters. Depending upon the pipe wall material and the solid particle, erosion could be high, leading to material loss and geometry deformation. In some cases, the shape deformation due to erosion can change the flow behavior and, as a result, the erosion rate. Thus, it is important to be able to model shape deformation.
