Fluid Mechanics   

Fluid Mechanics affects everything from hydraulic pumps, to microorganisms, to jet engines.  Purdue brings together a world-class group of researchers to model these behaviors in the computer, and then apply them to real-world situations.

Whether it’s air flowing over the blades of a turbine, or liquids coating a batch of pharmaceutical tablets, Purdue boasts one-of-a-kind facilities that enable researchers to explore new theories and set new standards: including the largest academic hydraulics lab in the country. Even at the microscopic or nanoscopic level -- even within the human body! -- Purdue researchers have the expertise to forge new discoveries every day.
