I was doing the spray injection simulation.
Water droplets was injected in the static air occupied cylinder by pressure-swirl atomizer with on inlet and pressure outlet. LISA model and ETAB model was employed. The parameters for the atomizer to abotain the initial condition of the droplets was; deltap=0.9MPa cone angle=28.3 radius=1.16mm massflow=0.3251kg/s Density probe normal distance=1mm(I just guess this parameter) As my understanding,because the continuous phase was static, it should be laminar flow,so no turbulence model should be employed. But the error message bring up when i run the simulation,that is " ERROR #002100004 has occurred in subroutine Out_Scales_Flu. | | Message: | | The Reynolds number is outside of the range expected based on the | | Option selected for the TURBULENCE MODEL. Check this setting, | | the values of the properties, mesh scale, consistency of units | | and solution values in the input file. Execution will proceed. | +---------------------------------------------------------------" Anyone willing to help ,thank you. I have difficulty in doing this simulation, if someone who have done this kind of work, i am grateful to your advice. |
