Spheres bring clarity to flow diagnostics

A Microsphere Technology product story
Edited by the Engineeringtalk editorial team May 23, 2008

Seeding material is optimised to deliver enhanced light scattering compared with traditional materials such as silver particles.

Microsphere Technology has developed a novel seeding material specifically engineered to provide substantial benefits to users in optical flow diagnostics such as particle image velocimetry and laser doppler analysis.

Working in partnership with Laser and Imaging Sciences, the new Isospheres seeding material has been developed and optimised to deliver enhanced light scattering compared with traditional seeding materials such as silver particles.

According to Dr Tom Johnston, Head of Research at MTL: "Our products are carefully designed using our novel patented process for coating glass spheres with titania".

"We use our expertise to ensure the particles demonstrate optimal buoyancy characteristics".

"Achieving a density close to that of water ensures virtually all particles remain in suspension, even at the lowest fluid flows".

"We can tailor the density of our spheres for optimal buoyancy within any liquid system".

Jean-Baptiste Richon, Head of Laser and Imaging Sciences, adds: "We have carried out very detailed laboratory evaluations on the microspheres".

"They give excellent results and we have further confirmed this in tests carried out by our customers".

"As a result we have just received our first commercial orders".

John Bamforth, MTL Director, confirms: "This is the first of a series of Isospheres products which will be launched for the flow visualisation community".

"MTL is actively preparing the launch of its next product, which is for the planar laser induced fluorescence (PLIF) application".

Full technical performance details of the Isospheres products will be released at the ISFV13 conference from 1st to 4th July 2008 in Nice, and at the International Symposium on Applications of Laser Techniques to Fluid Mechanics from 7th to 10th July 2008 in Lisbon.
