The application range includes aerodynamics, hydrodynamics, spray diagnostics, multiphase flows, turbulent boundary layer flows, combustion diagnostics and many more. We are recognized for our innovation and quality and we are applying emerging technologies to meet unique and challenging measurement requirements from you.
Quality fluid mechanics solutions from Dutco Tennant LLC are appreciated around the world. In this segment, we provide Particle Image Velocimetry which is a non-intrusive laser-optical method used for determining velocity distribution in fluids. The PIV system may be of different complexity, and depending on the application type it may vary widely, but then the basic principle of PIV remains the same.
Our fluid mechanics systems have been specifically entrusted by researchers to take measurements of fluid flow velocity, droplet size, and all the associated flow and sizing statistics at a point, over a planer region or for a complete three-dimensional volume, in a wide range of environments. The systems reliably measure three components of velocity, particle/droplet size and shape, number density, volume flux, temperature, concentration and many other parameters to provide you with the solution needed to resolve the problem you are working on. Many of our systems are laser-based which are non-invasive, meaning that the systems will have no disturbance to the parameters you want to measure, giving the most accurate and reliable measurement results.
In order to let the Particle Image Velocimetry (PIV) work, the fluid mechanics system is planted with light scattering particles, which are believed to follow the flow dynamics. For the instrument to work, the flow has to be illuminated by a concentrated light source, which could be a laser, and there is a special camera which acquires the reflected light from tiny particles present in the flow. The camera in the equipment takes two successive images which are matched with the two light pulses. The light pulse produced by the product is very short so that even a single particle may be recognized in the images without haziness. The software which does cross-correlation then measures the particles’ displacement between the first and second image. Since the time lapse between the two light pulses is known, you can calculate the velocity field.
