Physical geometry model
The geometry is a perforated plate that was designed using “Auto-CAD” design modeler (2017 version) to represent a real sand screen with similar specifications, Fig. 3(a) and Fig. 3(b) show the 3-D view and front view of the geometry, respectively. The structured geometry was then imported into ANSYS Fluent 2019 (R3) design modeler to create an enclosure, as shown in Fig. 3(c), so that the boundary conditions of the flow are defined in order to represent a basic fluid flow simulation through a
Velocity vectors and streamlines
In oil and gas industry, the equipment material and dimensions are carefully chosen so that the flow velocity is below the so called “erosional velocity”. Erosional velocity is defined as the velocity under which there is no presence of erosion (Arabnejad Khanouki et al., 2014). It can be seen in Fig. 6(a) that high velocity intensity is concentrated around the edges of the screen making it obvious to analyze the erosion rate and location. The sizes of the small particles are assumed to be
Conclusion
In this study, a CFD simulation has been conducted to evaluate the erosion on standalone screen (SAS). The discrete phase model (DPM) was employed to track discrete sand particles in a continuous gas flow. The sand tracking parameters were then introduced to four erosion equations, viz. Fluent generic, McLaury, Finnie and Oka.
Three erosion equations have shown fair agreement in their erosion patterns. Finnie equation, however, has shown totally different erosion patterns due to the limitation
