What is it about?
A wind tunnel test of a bump model that mimics a wing-body junction of a flight vehicle is used to compare to computer simulations. This paper compares the initial testing conditions produced by the wind tunnel vs. the computational models. It also gives some unique insight to how air moves around an aircraft-like body.

Why is it important?
Conducting experiments inside wind tunnels is often an expensive endeavor. From the fabrication of the parts, to the sensors and fixtures to measure the air flow, a lot of time is spent making sure that aerodynamic bodies are acting as we expect them to. Computer models are more efficient than physical experiments, but sometimes lack the accuracy that is critical in a flight scenario. Validation experiments are needed to identify where the models need improvement.
