The meaning ofturbulence is a sudden, violent shift in airflow.It creates up and down currents caused by irregular atmospheric motion. You can also define turbulence as that sudden jerking you sometimes feel in an airplane! So, what does understanding turbulent flow have to do with safe flying?

E: We’ve got three words for you here in vocabulary preview all about flying. M: Okay, so what’s our first one? E: Turbulence. M: Turbulence. E: Turbulence. M: Turbulence. E: So, turbulence. How can we describe this? M: Well, turbulence, when you’re in an airplane, basical...
Complete configurations often have laminar regions in their boundary layers; it is very helpful if a turbulence model can be “dormant” in such regions, meaning that its transport equations accept solutions with vanishing Reynolds stresses. Similarly, regions of irrotational and non-turbulent fluid, ...
Vertical wind shear—the increase inwind speedat higher altitudes—causes invisible clear-air turbulence, which can be severe enough to throw airplane passengers out of their seats. It terrifies nervous fliers and injures hundreds of passengers and flight attendants every year. ...
In that work, a hot-wire probe was fixed onto an airplane wing and flight turbulence data were recorded. The investigation of the autocorrelation function of the hot-wire data revealed the presence of a low frequency component in the signals. Further investigation concluded that this disturbance ...
