Answer by Peter Kämpf for How is windspeed scaled in wind-tunnel tests?
In order to achieve the same flow conditions, you need to match several similarity numbers. The most important one expresses the ratio of inertial forces to viscous forces within a fluid and is called...

It really depends on what data you need and the conditions you need it for.Let's say you want to test a scale aircraft model in a wind tunnel in order to predict the lift forces on the full-sized...

Let's say you have a scale model that is 1:10th the size of the real thing. You want to test this in a wind-tunnel.Do you also scale down the windspeed 10x? Why or why not? I would think it has to be...
