Fundamental Fluid Mechanics

Though fundamental fluid mechanics research is based on only a few straightforward underlying principles, the study of it is extremely challenging and complex.  As such, discovering new principles in the way fluids behave and interact is extremely rewarding.  TSI’s fluid mechanics research instruments team possess a vast range of experience and expertise in the understanding and practical application of experimental techniques and are ready to partner with researchers the world over to provide the ideal measurement devices for all fundamental fluid mechanics research.

TSI's Fundamental Fluid Mechanics Research Systems

Fundamental Fluid Mechanics experiments require measurement instruments that are precise and flexible enough to meet the needs of the researchers that use them. Below are TSI’s fundamental fluid mechanics product offerings that can open up new understanding in any area of fluid mechanics research.

  • TSI’s award winning V3V™ system takes fundamental fluid mechanics research to the next level with its 3-dimensional velocity measurements throughout a volumetric domain- providing researchers the complete 3-component velocity matrix in a volume up to 140mm x 140mm x 100mm instantaneously!  No need for laser sheet scanning, or relatively thin “thick light sheets”.
  • Particle Image Velocimetry (PIV), stereo PIV, and TSI-patented microPIV enhance fundamental fluid mechanics experiments and research methodology by adding state-of-the-art velocity measurements in a plane.
  •  TSI’s Laser Doppler Velocimetry (LDV) systems allow researchers to investigate flow point-wise.
  • TSI’s powerful Phase Doppler Particle Analysis (PDPA) technique - recognized throughout the spray industry as the current ‘gold standard’ in droplet size measurements -  helps fluid mechanics researchers  verify  accurate droplet and spherical particle size in multiphase flows.
Thermal Anemometry for Fundamental Fluid Mechanics Measurements

For over 50 years, researchers have looked to TSI’s thermal anemometers to make additional flow measurements in their fundamental fluid mechanics experiments.  Such instruments and their related applications include:

  • TSI’s Hotwire and hotfilm anemometers (constant temperature anemometers) provide high frequency response velocity measurements in liquid or gas domains, by introducing a small probe into a flow to obtain highly accurate velocity information. 
  • Constant current anemometers from TSI are used for high frequency response temperature measurements, important in some fundamental fluid mechanics research.
