Hi,
I need to demonstrate to some kids a fluids experiment which I can match the data with both CFD and theory (hand-calculation from analytical methods) and show how all 3 are used together. Since I don't have much funds for this I need to do it cheaply and I don't have access to a wind tunnel either. Something like Stoke's flow of a small sphere in syrup. I've also got to do this for FEA, so thought about bending and twisting of a beam. Can anyone suggest some other ideas for this? Thanks |

Something involving a simple incompressible flow? So maybe look at what examples are used in intro to fluid dynamics text books?
Otherwise maybe do a scaling of a full scale model (Pi numbers & non dimensional numbers) of a flow of water over a dam wall or through a narrowing in a channel as this demonstrates theory, calibration and should go well in the CFD if you keep it a laminar flow. Maybe try laminar flow around a shape that has a known coefficient of drag in a similar situation? |
