FAYETTEVILLE, Ark., Sept. 15 -- The University of Arkansas issued the following news release:
Before a jet engine is ever built, it is flown thousands of times inside a computer. Each simulation must reckon with turbulence, the churning, chaotic motion of air and water that no equation has fully solved.So, engineers rely on mathematical models that approximate turbulence closely enough to design around it.
Keith Walters, professor and associate department head for graduate programs in the Department of Mechanical Engineering at the U of A, spent three decades building those models.Some of his work is built into commercial simulation software used by engineers around the world. Examples include the k-kL-w turbulence model, which was origin...
