Erosion Project Description
This simulation is modeling erosion in the bent pipe by a Two-way DPM Erosion Model to see the erosion rate in the pipe using ANSYS Fluent software. Working fluid is water liquid, and sand particles are DPM injections. Particles are inert and with no initial velocity.
Geometry & Mesh
The 3-D geometry of the present model is carried out using Design Modeler software.
The meshing of this present model has been generated by ANSYS Meshing software. The mesh grid is unstructured with no element quality lower than 0.53, and the total cell number is 448925. the figure below shows an overview of the performed mesh.
Erosion CFD Simulation
To simulate the present model, several assumptions are considered, which are:
- The solver is pressure-based.
- This Simulation is steady.
- The effect of gravity on the flow is considered to be -9.81 m.s-2 and along with the y-axis in the present model.
The following is a summary of the steps for defining the problem and its solution.

Results
At the end of the solution process, two-dimensional and three-dimensional velocity, erosion rate, particle tracking counters are obtained. This 3-D simulation shows how sand particles erode the pipe from its bend. Also shows the effect of bend on pressure and velocity field on the bent pipe.
