Hi there
Someone can give me an orientation about this simulation in fluent? First. I'm trying to simulate a spiral concentrator with DPM with the next parameters: →steady state analasys →Gravity in Z direction: -9.81 m/s2 →Viscous model: RNG k-e model, swirl dominated flow condition →Discrete phase model: Anable → Interection with continue phase Update DPM source ... Unsteady Particle Tracking →Injection: Rosin-Rammler | Injection type: Surface | Total flow rate: 0.139 kg/s | magnitud velocity: 0.9 m/s | stop time 10000 →Fluid material: Water-liquid →Boundaries: Velocity-inlet:0.9 m/s | DPM condition: escape outlet and surface: DPM condition: escape | Pressure outlet and surface: 0 wall: DPM condition: reflect →standard initialization from the inlet The problem is with the results because the particles don't follow the trajectory of the spiral, they just can't fully develop So I don't know if the model is wrong or the speeds are low, also I tried to simulate whit Eulerian and in the transient state but the results are worse than this Any suggestion? |
