We may or may not recognize it, but fluid is a very integral part of our everyday lives. It decides everything from our fuel economy to (in some cases) how cool our computer runs. Until now, there was only one key way of deciphering the mechanics of fluids, and that was the Prandtl equation, developed in 1904. Sadly though, the Prandtl equation has many limitations, including only having the ability to calculate only two-dimensional problems, and a steady flow (such as that of a car traveling slowly). Thanks to a breakthrough by MIT’s George Haller, that’s all about to change.

A recently developed new equation, which is a product of four years of work by Professor Haller, will apply to three-dimensional and unsteady flows. This was confirmed with the aid of Thomas Peacock, the Atlantic Richfield Career Development Associate Professor at MIT, who lead experiments in order to validate the equation. Professor Peacock states, “This is the tip of the iceberg, but we’ve shown that this theory works.” The new work will probably go down as one of the greatest scientific advances of the decade, if it survives the peer review that will come.

This innovation in the mechanics of liquids will have an overwhelming influence on many industries, including aerospace, automotive and even computers. With these breakthroughs in calculating how liquids will act and perform in different environments, there’s no doubt that your PC’s liquid cooling system will soon get an overhaul.
