How The Density Of Air Changes On A Regular Day
The density of air changes throughout the day. But, how much error does that create for your experimental data and your CFD validation data?
This podcast demonstrates how this error (on a typical day) affects the flow physics and force measurements your bluff bodies and streamline bodies.
If you're not measuring the density of air during your experiments, then you have substantial errors in your data, and you don't even know it. You can't get away from it. So, you better deal with it now rather than later because the later you leave it, the more problems it will create for you.
