Dantec Dynamics - Particle Image Velocimetry (PIV) Measurement Technique

Particle Image Velocimetry (PIV) is a non-intrusive laser optical measurement technique for research and diagnostics into flow, turbulence, microfluidics, spray atomization and combustion processes.

Dantec Dynamics - Model 2D3C - Stereo PIV Systems

Stereo PIV is a method for measuring three velocity components in a plane (2D3C) based on the principle of parallax. By placing two cameras so that they observe the light-sheet plane from two different angles, you obtain slightly different two-velocity component vector maps from each camera due to the parallax effect. The differences between them arise from the third, out-of-plane velocity component and the geometrical configuration of the two...

Dantec Dynamics - Model 3D PIV - Volumetric Velocimetry Systems

Volumetric flow field information with 2, 3 or 4 cameras. Volumetric Velocimetry (VV) also known as 3D PIV or Tomo PIV provides truly volumetric velocity data, using up to four cameras with telecentric lenses, and a thick light sheet or a scanning thick light sheet. Time-resolved VV solutions using time-resolved CMOS cameras, as well as “classical” solutions with CCD cameras are available. For low to medium seeding concentration, Particle...

Dantec Dynamics - Time Resolved PIV Systems

Progressing the Essential Time – Space Correlation. Dantec Dynamics was the first company to introduce Time Resolved PIV systems based on practical Nd:Yag lasers and a new high performance, high speed camera. Today Time Resolved PIV is an affordable option for research in fluid mechanics, thus adding the essential time-space correlation to our experimental fluid mechanics world.

Laser-Induced Fluorescence in Liquids Phase

Planar Laser-Induced Fluorescence (PLIF) is an optical diagnostic technique widely used in fluid applications. PLIF has proven to be a valuable tool for flow visualization as well as for quantitative whole-field measurements of concentration and temperature in liquid flows. Applications can be found in process engineering, biomedical engineering, and fluid dynamics research.

Laser Doppler Anemometry (LDA)

Laser Doppler Anemometry (LDA), also known as Laser Doppler Velocimetry (LDV), is an optical technique ideal for non-intrusive 1D, 2D and 3D point measurement of velocity and turbulence distribution in both free flows and internal flows. Science and industry apply our LDA systems to gain a clearer understanding of fluid mechanics. The measurement results are important steps in fine-tuning product designs to improve aerodynamic efficiency, quality and...

Constant Temperature Anemometry (CTA) / Thermal Anemometry

Constant Temperature Anemometry (CTA), also known as Thermal Anemometry, is a technique for the measurement of turbulence in 1, 2 or 3-dimensional gas and liquid flows, using hot-wire or hot-film probes inserted in the flow. CTA is particularly suitable for the measurement of flows with very fast fluctuations at a point (high turbulence) and the study of flow micro structures, where there is a need to resolve small flow eddies down to the order of...

Hot-wire and Hot-film Probes

Dantec Dynamics offers a complete probe system for use with Constant Temperature Anemometers (CTA). The CTA anemometer is today's most widely used instrument for measurement and analysis of the micro-structures in turbulent gas and liquid flows. The CTA probe program comprises a variety of probe types and probe configurations. There is a probe for almost any measurement situation.

Traverse Systems

Many experiments using LDA and PDA technology require mapping of the fluid velocity in space. Often, velocity and/or size information from hundreds or thousands of positions in the flow is required. The high resolution of the Dantec Dynamics traverse systems meets these requirements as well as those for boundary layer measurements. It is available as 1D, 2D and 3D configurations. The system permits easy upgrade of a 1D system to 2D or 3D.

Dantec Dynamics - Phase Doppler Anemometry

Dantec Dynamics' Phase Doppler Anemometry (PDA) (also known as Particle Dynamics Analysis or PDPA) systems measure the size, velocity and concentration of spherical particles, droplets or bubbles suspended in gaseous or liquid flows. A very common application is the analysis of atomized liquids (sprays) in e.g. fuel injection, spray painting, liquid metal spray and pharmaceutical sprays.

Dantec Dynamics - Interferometric Particle Imaging System

Interferometic Particle Imaging (also known as ILIDS) measures the size and velocity of spherical, transparent particles such as spray droplets, glass beads or air bubbles in water. The main component are a laser with light sheet optics, a dual camera system and a software package. An IPI add-on is available for DynamicStudio, Dantec Dynamics' imaging software platform.

Shadow Sizer

The DynamicStudio Shadow Sizer measures size, shape and velocity of particles using backlighting and image analysis software. The Shadow Sizer can measure a wide range of particles types including bubbles, liquid droplets, solid particles and any object with a well-defined contour. Data is analyzed by DynamicStudio and includes histograms of size distribution, spatial distribution plots, cumulative histograms and tables.

Rayleigh Thermometry

The analysis and optimization of combustion processes requires accurate measurement of several parameters, out of which temperature distribution is one of the most important. Designed for clean combustion environments with high temperature gradient, Dantec Dynamics’ Rayleigh Thermometry system provides all the tools needed for measurements of two-dimensional temperature maps in combustion and heat transfer studies. The technique offers very wide...

Laser-Induced Incandescence (LII) System

Soot is considered a hazardous pollutant emission, and is typically a result of incomplete combustion processes and is thus also related to combustion performance. Laser-Induced Incandescence (LII) is a laser-optical measurement technique dedicated to soot diagnostics. LII can provide measurements of soot volume fraction in e.g. Diesel engine exhaust and even instantaneous images of soot distribution during the formation inside a running IC engine.
