Creating New Solver: For particle-laden compressible jets1 Attachment(s)
Hello OpenFoamers
I am a new user of OpenFoam and I am trying to set-up a particle-laden under-expanded supersonic jet issuing into an open atmosphere. Note, before I started OpenFoam, I ran fluent and got a converged solution for this problem Here are details of OpenFoam simulation: --------------------------------------- Solver: rhoCentralFoam Grid: axi-symmetric grid imported from Fluent using fluentMeshtoFoam I.C: I used the converged Fluent solution as initial condition for openFoam I managed to get a converged steady state solution for this problem without particles Particle laden jets: !---------------------------------- Now I am trying to run a particle-laden jets. Since the solver rhoCentralFoam does not have Lagrangian Particle Tracking in it, I realized that I have to create a new solver. I came across the icoLagrangianFoam solver which is basically a particle tracking solver for an incompressible flow. I found a nice tutorial "Tutorial icoLagrangianFoam/SolidParticle" by Auerlia Vallier (google for file name: Tutorial_icoLagrangianFoam_reviewed.pdf). I used that and managed to implement particle tracking in the rhoCentralFoam solver (which is a compressible solver). I called this new solver rhoCentralParticleFoam This works well. But the problem is that the drag model in the original icoLagrangianFoam is a very simple constant drag model. I want to implement the standard drag model which is a function of particle Reynolds number based on the stokesian drag for spherical particles. Chapter 5 in the tutorial (Tutorial_icoLagrangianFoam_reviewed.pdf)describes how to implement this drag model. When I did these changes I get some compilation errors that I cannot comprehend. I admit that I don't know c++ and I am not able to figure out the exact problem. Can someone help me to fix these compilation errors ? I have attached a tar file which contains the codes I am using for this solver |
