Analysis and visualization

Analyses

The LOCIE analysis platform consists of various types of devices designed to assess indoor air quality and characterize energy conversion processes using biological means (methanization, microbial fuel cells) or physical means (organic photovoltaics).

Visualization

LOCIE has:

  • a high-resolution 15MPix AVT GE4900 camera.
  • high-power lighting devices.
  • A PIV (Particle Image Velocimetry) measurement bench consisting of a dual-pulse laser (DualPower 65-15) and a dual-frame 4MPix camera (FlowSense 4M). An automated laser and camera movement system allows relatively large areas to be examined with a high degree of precision. It is used in numerous applications to characterize fluid flows (water, air, etc.) by measuring velocity fields. Examples of applications: building aerodynamics ("double skin" walls, control of air flows in wood frame walls), natural convection in a closed cavity (boundary layer, thermal plume), green walls.
  • a particle generator to seed the air with tracers.
  • A macro lens for performing PIV in microfluidics (in microchannels).
  • A laser tomography system that allows visualization of a cross-section in a fluid flow (Laser RayPower 2000 + Basler camera).
  • An infrared thermography system that measures the temperature field of a surface remotely based on infrared light flux.
  • two high-speed cameras.
