Summary | 0003932: Faulty implementation of pressure gradient force in Lagrangian Particle Tracking | ||||
Description | The pressure gradient force under src/lagrangian/parcel/submodels/Momentum/ParticleForces/PressureGradient/PressureGradientForce.C is implemented as m*rho_c/rho*(Du/Dt). However, the pressure gradient force is given by V_p*grad(p), where V_p is the particle volume. The model currently implemented only holds if the viscosity of the carrier phase is negligible. Thus, I think that that force should be re-implemented. I am not sure how to contribute code, but I could submit a patch or a pull request. | ||||

How do you propose to calculate V_p*grad(p) for the particle given that the pressure distribution around the particle is not solved for? Do you have a paper which provides details and validation of alternative methods to calculate the particle pressure gradient force? |
