Hi CFDEM forum,
New here, first post. Hence, naive question:
I want to study multiple solid particles (Lagrangian) in a flow field, with 2-way (P-F) and 4-way (add P-P collisions etc) couplings, and full momentum exchange between particle and flow (i.e. back-force). I also want largish particles (not point-particles) such that I will require full resolution of all forces acting on the particle surface. This will require fine scale meshing of the particle surface and nearby flow field. The particles are free to move i.e. Lagrangian. As this is a fundamental study, everything must be resolved in Eulerian frame, including the particle motion. This will inevitably require dynamic re-meshing following the particle motion. The fluid is incompressible Newtonian with constant viscosity, and the the flow would be fully resolved i.e. DNS solver with coupled back-force, etc.
I am thinking of starting with just 2 particles, eventually progressing to 3,4, .... in due course. The flow is initially laminar, maybe just a uniform flow to start off with, and later uniform shear, etc.
Obviously, a highly optimized parallel code with dynamic re-meshing is desirable.
The question is, does CFDEM have any codes for this? If not, how close to the above are the present codes? If not possible, any recommendations for other open source codes?
Thank you
