An ERT system gives the images based on the internal conductivity distribution of contents of geometry (i. e. like hydrocyclone, vertical pipe flows, bubble column etc.) from the measured boundary voltages. We are equipped with ITOMS ERT with a capturing data range of 1000-2000 dual frames per second. We have 76mm conical and 100mm  cylindrical geometries with 16 electrode sensors. Our main focus is to work the experiments with various designs and operating conditions through the ERT for slurries of various concentrations. The obtained phase concentration profiles from the ERT are used to validate against the CFD. Hence a variety of designs can be tested through CFD.

We are equipped with PHOTRON camera with 1 MP at 2000 fps, 120,000 fps at 128X128 pixel, shutter speed of 1µs. We also possess 12X high magnification zooming lens for micro study, automatic copy stand for flow measurements. This camera us used to measure the solid flow velocities in the pilot scale fluidized bed, two-phase air-core measurements in the acrylic bases hydrocyclone systems, bubble velocity measurements in bubble column and measurements in micro channel flows

LDA system is used to measure the point based velocities in a transparent or semitransparent flows on the basis of Doppler shift in a laser beam. This technique is also non-intrusive and can measure all the three velocity components. Neutrally buoyant seed particles are used to scatter the light. The seed particles are illuminated by a known frequency of laser light using optical transmitter. The scattered light is detected by the optical receiver. We have ARTIUM LDA with a velocity measurement range from 1 mm/sec – 80 m/s ± 0.1%. The fluctuating velocity measurement range from 0.1 µm/s to 5 mm/s. We focus on measuring point based velocities in the hydrocyclones, vertical pipe flows etc.

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. Standard PIV measures two velocity components in a plane (2D2C) using a single CCD or CMOS camera. We are equipped with DANTEC PIV with 200 ns interframe for high speed applications. Time resolved PIV benefits from the advances in CMOS camera technology to acquire high resolution PIV images at frame rates up to 16000 fps (frames per second) with full camera resolution. Our work focuses on the measurement of velocities over a plane of given equipment (Bubble column, Column flotation). This measurements will be further used to validate our CFD predictions.

MICROTRAC S 3500 particle size analyzer with a sample delivery controller uses tri laser technology to provide accurate and reliable particle size information in both wet and dry mediums. Particle size range varies from 0.02 to 2860microns. It Works on the principle of light scattering technology using Fraunhofer diffraction method. Improvements include Mie scatter theory and differential polarization techniques. It is mainly used to measure the sample size distribution that are collected after the drying from cyclone systems.

An ECVT system gives the images based on the internal permitivity distribution of contents of geometry (i. e. like fludization,  vertical pipe flows, bubble column etc.). We equipped with TECH4IMAGING ECVT sensor with 24 channels and 102mm straight cold flow section. It is mainly using for the purpose of understanding the fundamentals of gas-solid fluidized beds.

We have GLAB developed compact optical fiber systems for the measurement of both particle concentration and particle velocities under typical fluidization operating conditions.
