FLUID MECHANICS

TSI Incorporated serves the fluid mechanics and particle diagnostics researcher with state-of-the-art transducers, controls, software, and complete measurement systems. Its instruments provide flow and particle information in a wide range of applications. With a worldwide reputation for innovation and quality, TSI is adept at applying emerging technologies to meet unique measurement requirements.

 

Our products have been used to measure flow velocity, turbulence, and all the associated properties at a point or over a planar region in a wide range of environments, varying from simple, to complex, to hostile. They also measure particle size, velocity, number density and volume flux of spherical particles, droplets, or bubbles in similar environments. TSI systems also measure noninvasively temperature, concentration and other scalar properties.

 

TSI sensors have, for example, measured wind velocity on Mars, studied air flow around buildings, obtained droplet diameters and associated properties in sprays, identified flow patterns around piers and other underwater structures, diagnosed flows associated with turbomachinery, and revealed key details of combusting flows and flames.

V3V™ CAPTURES 3D VORTEX SHEDDING FROM A SPHERE — March 27, 2008-  TSI's patented Volumetric 3-Component Velocimetry (V3V™) system was recently used to capture the volumetric flow structure downstream of a smooth sphere in cross flow. Three-dimensional vortex shedding was quantified in one instantaneous capture from the unique 3D camera in a volume 90 x 90 x 140 mm at Reynolds number 2200. Hairpin-like vortices formed downstream of the sphere and were shed alternately along opposite sides of a plane of symmetry. TSI INC. V3V SYSTEM IS 2008 R&D 100 WINNER — July 1, 2008- TSI Incorporated’s Volumetric 3-Component Velocimetry (V3V) System was awarded the prestigious R&D 100 Award on July 1, 2008. The R&D Award is selected by a panel of judges and editors from R&D Magazine, and is judged on design, development, test, and production of the product. It is one of the 100 most technologically significant products introduced into the market place in the past year.NEW PIV-EXPRESS STARTER SYSTEMS ANNOUNCED — January 1, 2009 - Get on the PIV-Express!TSI’S V3V SYSTEM RESULTS ON YOUTUBE.COM — February 17, 2009 - For the first time, you can now view TSI’s V3V System demo and results on Youtube.com. INVITATION TO TSI SEMINAR IN COOPERATION WITH INSEAN — November 04, 2009 - TSI, the leading worldwide manufacturer of aerosol measurement solutions, invites you to join us for a discussion of innovative solutions for Measurement of Fluid Flow. V3V™ SYSTEM – VOLUMETRIC 3-COMPONENT VELOCIMETRY — September 11, 2007-  The V3V™ System is the only 3-dimensional, 3-component (3D3C) velocity measurement system for your complex 3-D flows in a true volumetric domain. Once the image of your 3-D flow field is captured, you can see the velocity results in seconds, rather than minutes, thus allowing you to DISCOVER your instantaneous flow field quickly and accurately. The patented Camera probe in the V3V System uses three apertures to obtain the locations of the seed particles in the 3-D domain up to 140 mm by 140 mm by 100 mm. With 12 million total pixel resolution it is not only powerful but also simple to use. It is as easy as point and shoot, with no need for focus adjustment or complex alignment procedures. The measurement of 3-Components of velocity in a truly volumetric region using the V3V System is all you need for your flow measurements. TSI ANNOUNCES 2010 SEMINARS AND WEBINARS FOR RESEARCH AND ANALYTIC APPLICATIONS — February 17, 2010- TSI Incorporated will once again offer a wide range of educational and networking opportunities for researchers in the fields of aerosol science and fluid mechanics to participate in throughout 2010.  In particular, TSI experts will host a running series of seminars and webinars aimed at providing ongoing professional development, information on the latest measurement solutions, and additional system training. TSI also hopes that such events will serve as a forum for more in-depth scientific discussions and idea sharing among researchers.

PDPA AND LDV TRADE-IN PROGRAMS ARE BACK FOR 2010 —  UPDATE YOUR PIV CAMERA THROUGH OUR 2010 TRADE IN PROGRAM — TSI cameras are well-known for their performance, compact size, and long-lasting durability resulting from the protective CCD mask. After five to ten years, however, technology has advanced to the point where new cameras offer significantly greater speed, resolution, and ease-of-use. That's why we are offering this limited-time trade in program for customers with PIVCAM10-30, Kodak ES1.0, PowerView 2M, and PowerView 4M cameras. Take 15% off the price of a new camera when you trade in your old camera for the sensitivity and resolution of a new PowerView Plus 2MP or 4MP camera. The old camera does not even have to work!
