Specification
Nano Fluid Interferometer
Objective:-
1.Characterization of Nanofluids like Ag/Au & Ferrofluids etc.
2. To evaluate modest nanoparticles concentration in the fluid for significant enhancement of its property.
3. Prediction of enhanced thermal conductivity due to the suspension of
the metallic nanoparticles with a very low concentration into the
polymeric fluids.
4. Sound Velocity and compressibility of nanoparticles with liquid suspension.
5. Study of Phase transition and to detect/assess weak and strong molecular interactions in Nanofluids.
6.To determine the extent of complexation and calculate the stability constants of such nanofluid complexes.
Working Principle:-
Nanofluid Interferometer generates the sound wave in Nanofluids of different concentrations at different temperatures.
This instrument is low cost & effective tool to optimise the
concentration of nanoparticle for best results to achieve the desired
property.
In this instrument, Ultrasound waves of known frequency are produced by a
Piezo-Electric transducer and its wavelength is measured with digital
micrometre with high accuracy within ±0.001mm.
From the knowledge of frequency (f) and wavelength(λ); the compressibility of nanofluid is determined by the following formula :
Sound Velocity in a nanofluid.
Adiabatic compressibility whereρ is the density of nanofluid.
Description:
The Nanofluid Interferometer consists of the following parts:
Wave Generator.
Nanofluid Cells.
Temperature Controller Unit. (RT to 90°C).
Nanofluids – Chemicals to make Ag nanofluid in various concentrations.
