Provisional Patent Application Filed

Fluid mechanics enable the accurate and analytical characterization of complex fluids, their flow, and their properties. However, many of the measurement techniques utilized to measure the frequency-dependent coefficients of viscoelastic fluids involve the use of expensive measurement devices and time-consuming experimental set-ups.  This technology proposes an inexpensive and relatively swift procedure whereby the necessary fluid properties (frequency-dependent coefficients) of complex, viscoelastic fluids can be determined.  

Reference Number: D-1037 

Market Applications:

The technology significantly reduces the costs associated with measuring viscoelastic properties of complex fluids.

  • Industrial Applications (Product testing for various products such as paint, adhesives)
