Science Dictionary
turbulence   (tûr'byə-ləns)  Pronunciation Key 
Chaotic or unstable eddying motion in a fluid. Avoiding excessive turbulence generated around moving objects (such as airplanes), which can make their motion inefficient and difficult to control, is a major factor in aerodynamic design.
