I modeled an unsteady multi-component (3 species) injection in the open air (to model spray in the open air)
DPM : two-way / unsteady/ solid-cone / multi-component ( 2 of 3 components evaporated)/ injection duration 0.1 s / injection velocity 100 m/s / max. number tracking 1000 /
Continuous phase: LES (WALES)
time step: 0.0005,
but evaporated particle=0, why does it happen?
Please help me in this issue.April 11, 2022 at 12:34 pmRobAnsys EmployeeIf it's multi component and one component doesn't evaporate there will always something left.
April 11, 2022 at 2:17 pmMasiSubscriberThank you for your reply! You mean that in the solution console,evaporated=0 because one of the components is non-evaporation. So, the solution is correct? and the other components' evaporation are not reported in output?
April 11, 2022 at 4:00 pmRobAnsys EmployeeThe report is for when that parcel is evaporated: so if one component does not evaporate no droplets are ever going to reach that state. Double check you have some of the non-evaporating component in the particle mixture for the injection.
April 11, 2022 at 4:56 pmDrAmineAnsys EmployeeAlways check DPM summary. Particles with non volatile approach will never fully evaporate.
April 11, 2022 at 10:16 pmMasiSubscriberHi DrAmine, My components are Alcohol, Hydrofluorocarbon-134a and the other one is a specific material, thatAlcohol and Hydrofluorocarbon-134a are 100% volatile materials and the third one is non-volatile. when I change the geometry of nozzle the evaporation happens (in the report). but with a specific shape, it is " evaporated=0" (in the report).But After completion of the calculation, when comparing the result of both of them seem that they are the same.
