Modeling Blood Flow for Heart Pumps
Modeling the flow of complex liquids through rotors or axial pumps is difficult when the liquid is complex and contains solids that deform or can fracture, like blood. Supercomputers are helping these researchers and heart pump makers ensure shear is minimized.

Fluid engineers have long known that fluids must stretch and fold to mix—it’s been textbook stuff for a century. But until now, it was impossible to differentiate folding form mixing when mixing was actually done. Now, by adopting new mathematical tools used with glassy solids, two Yale researchers have isolated the stretching in an experimental setting. What’s left is the folding.

In the United States, the National Institute of Standards and Technology (NIST) oversees the development and implementation of standards for measuring process flow for a variety of industries. To achieve the lowest possible calibration uncertainty, NIST subjects the customer's meters to extensive testing lasting several days. Uncertainties can be as low as 0.21% at a 95% confidence level.
