Our advanced measurement solutions, including NDT and strain/stress measurement systems, allow you to reduce development costs and time to market by optimizing vehicle aerodynamics, engine design and thermal comfort. Shortening the development Process Greater focus on improved fuel economy and emission reductions, along with a growing consumer demand for comfort, safety and performance, have created fierce competition in the automotive industry. In order to gain a competitive edge, manufacturers must find efficient ways to accelerate product development. Dantec Dynamics offers a wide range...

Improving Vehicle Aerodynamics Reducing Drag Our instrumentation is widely used in automotive wind tunnels for determining and maximizing the aerodynamic efficiency of the underbody, rear end, wheel arches and side mirrors. Laser based diagnostic systems such as Particle Image Velocimetry (PIV) and Laser Doppler Anemometry (LDA) can be placed outside the test section to measure air flow nonintrusively, both in model and in full scale wind tunnels. Rapid flow field measurements can be made with PIV, helping to identify wake vortices and other spatial flow structures. LDA can measure in...

Reducing Noise CTA is well suited for aeroacoustic experiments, studying the turbulence spectra and hence noise generation. Its analog velocity signal can be analyzed by spectrum analyzers, and can be correlated with microphone signals to study the interaction between the sound field and turbulence. illumination. Right: PIV result, velocity vector field. The spatial behavior of the flow can be related to the sound field using probe arrays with multichannel CTA systems. LDA is well suited for boundary layer...

Enhancing Engine Performance Improving Fuel Economy and Reducing Emissions Optimizing Fuel Injection and Mixing Fuel injection and distribution are key processes in energy production and the quantity of pollutants emitted from engines, gas turbines and burners. Understanding and optimizing fuel atomization, vaporization and mixing require advanced measurements to characterize technical alternatives. The uniformity of droplet distribution in the combustion chamber is influenced by spray geometry parameters including cone angle, position and length. High speed cameras freeze the droplet...

Measuring Fuel Spray Temperature Minimizing Soot in Diesel Engines The air-fuel ratio is directly influenced by the spray droplet temperature and fuel vapor concentration in the combustion chamber. The new two-color Laser-Induced Fluorescence (LIF) technique can be applied to measure fuel spray temperature and provides data on the correlation between injection conditions and spray temperature for improvement of CFD models. Soot is a by-product of incomplete...
