Hi ,
I am doing an experiment on releasing a spherical body (polypropylene material) inside a small tank. It moves up solely due to buoyancy.On top of tank there is an aluminium plate of 10 cm thickness (fixed on top),to which the spherical object collides. I have recorded the velocity profile in lab. I am trying to simulate the same in flow 3d. But max velocity varies in my flow3d and real experimental results. for eg. at 5cm depth (from the aluminium plate) when the model is released its max velocity during collision is 0.28 m/sec while the Flow3d model gives max velocity as 0.16 m/sec. I have tried with different mesh sizes but it always gives me max velocity around 0.16m/sec. Please Advice. |
