Hourglass CFD Simulation Using DDPM and DEM, ANSYS Fluent Training
In this project, an Hourglass with the DPM model was simulated, and the results were investigated using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis. The present model is designed in 3-D using SpaceClaim.
The meshing of this present model has been generated by ANSYS Meshing software. The mesh type is Structured, and the total cell number is 244675. Also, due to the nature of the present problem, the transient solver has been enabled.
Methodology
In this research, hourglass simulation was investigated using the DPM model. The particle path inside the hourglass was also observed using Ansys Fluent software. While the DPM strategy for CFD solutions is a great way to compute particle flow studies that reduce computational costs, this approach fails to provide reliable answers for simulating dense particles with concentrations greater than 10% by volume.
DDPM (Discrete Concentrated Phase Method) is used in CFD projects to solve this problem. The discrete element method, or DEM, is a numerical method for calculating the interaction of large numbers of small particles.
Despite the very close relationship between DEM and the “Molecular Dynamics” simulation method, features such as degree of rotational freedom, particle contact, and complex geometry generally distinguish this approach from other options.
This method is based on an explicit numerical procedure examining the interaction between particles through contact and particle motion. The ability of the DEM model allows the user to consider the motion of particles as the mass of a moving point, which includes the shape and volume of the particles.
In addition, an injection-type file was used to insert 92,000 particles into the hourglass in zero seconds. Moreover, the laminar model is used to solve the fluid flow equations.
Conclusion
After the simulation, the particle tracking values in the hourglass are extracted, and the animation is attached.
