The CREC fiber optical probes are based on the use of fiber optic sensors that consist of an emitter optical fiber and a receiver optical fiber, combined with GRIN lenses (Graded Refractive INdex Lenses).
The CREC-GS sensor generates a focal region with high light energy density 5mm away from the probe tip. Solid particles or bubbles crossing the focal region are detected with minimum flow disturbance.
These optiprobes have been successfully employed in downflow gas-solid reactors and dense phase fluidized beds, to characterize solid flow patterns.
The CREC - GS Optiprobes can be used to:
Measure axial particle cluster velocities, cluster sizes and solid fractions in gas - solid catalytic reactors.
Characterize bubble flow in gas - solid fluidized beds.
Support CPFD (Computational Particle Fluid Dynamic) numerical calculations.
