Hello, Foamers!
I'm really new with OpenFoam and now im struggling with some problems. Now, Im doing a simulation , coupling VOF to LPT . The problem is from the bubble velocity when they got injected through the inlet into the water domain. It too high compare with the experiment data which is the maximum velocity of particle was 2.4 m/s compare with 0.4 m/s of the experiment data . Below is my injection part in KinematicCloudProperties. Code:
injectionModels { model { type manualInjection; massTotal 1e-7; // total mass to be injected (kg) SOI 0; diameters 4e-3; parcelBasisType mass;//fixed; nParticle 1; positionsFile "kinematicCloudPositions"; duration 1000; parcelsPerSecond 1;//1e1; U0 (0 0 0); volumetricFlowRate 2.25e-6; //volumeRate 9e-10; sizeDistribution { type fixedValue; fixedValueDistribution { value 4e-3; } } } } Is there anyway to control the Injection velocity of particle ? How OpenFoam calculate this velocity ? What variable/quantity effect to that Inject velocity value? Thank you so much for spending your time reading this post! Have a nice day ! Any help or suggestion are really appreciated |
