SESSION 6 - The Feasibility of Very Large Scale PIV and Tomographic PIV

Dr. Callum Gray, CEO

SESSION 6 - LaVision Inc

The total field of view (FOV) over which PIV measurements may be made depends on a few parameters including available laser energy, camera sensitivity and resolution and seeding light scattering efficiency. Current camera technology affords high sensitivity and resolution while PIV lasers routinely deliver pulse energies up to 400m . With the use of various seeding materials we consider the maximum FOV and volume that may be measured by Planar PIV and Tomographic PIV respectively.

Dr. Callum Gray has been CEO of LaVision Inc since 2001 and is responsible for all LaVision activities in the USA, Canada and South America. LaVision is widely recognized as the leading supplier of Particle Image Velocimetry systems worldwide and has been proactive in the fundamental development of flow mapping systems extending the well known PIV technique from a planar to volumetric technique with Tomographic PIV. In addition to PIV LaVision develop and deliver imaging systems for combustion diagnostics, spray analysis, material strain and deformation measurement. LaVision have also developed a series of sensors for R&D and process control. Previously Technical Director of Optical Flow Systems Ltd in the UK Dr Gray developed a variety of imaging systems including PIV and Stereo PIV and was responsible for some of the very first commercial PIV systems delivered in 1991. Earning his PhD in 1989 from Edinburgh University Callums thesis described a film based PIV system he developed for mapping velocities within spilling and breaking waves for improved estimation of slam and drag forces on offshore structures.
