| Summary | 0003305: Problem with TomiyamaLiftForce in Lagrangian module | ||||
| Description | In the calculation procedure for TomiyamaLiftForce, Eotvos number is used in pow operation (see src/lagrangian/intermediate/submodels/Kinematic/ParticleForces/Lift/TomiyamaLift/TomiyamaLiftForce.C) But Eotvos number can be negative due to its definition (see src/lagrangian/intermediate/parcels/Templates/KinematicParcel/KinematicParcelI.H): return mag(g & dir)*(rho - rhoc)*sqr(d)/max(sigma, rootVSmall); Here, (rho - rhoc) becomes negative if particle density is less than rhoc. | ||||
| Steps To Reproduce | Run DPMFoam with TomiyamaLiftForce enabled and particle density set less than fluid density. | ||||
| Tags | No tags attached. | ||||
