OBJECTIVE :

1. Characterization of Nanofluids like Ag/Au Ferrofluids etc.2. To evaluate modest nano particles concentration in the fluid fo rsignificant enhancement of its property.3. Prediction of enhanced thermal conductivity due to suspension of the metallic nano particles with very low concentration in to the polymeric fluids.4. Sound Velocity and compressibility of nano particles with liquid suspension.5.Study of Phase transition and to detect/assess weak and strong molecular interactions in Nanofluids.

WORKING PRINCIPLE :

Nanofluid Interferometer generate 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 knownfrequency are produced by a Piezo-Electric transducer and its wave length is measured with digital micrometer with high accuracy within ±0.001mm.From the knowledge of frequency (ƒ) and wavelength(λ); the compressibility of nanofluid is determined by the following formula :Sound Velocity in nanofluid v =λ.ƒAdiabatic compressibility ßad=(p.v2)-1where ρ is density of nanofluid. 

DESCRIPTION

The Nanofluid Interferometer consists of the following parts:(i) Wave Generator(ii) Nanofluid Cells(iii) Temperature Controller Unit. (RT to 90°C)(iv) Nanofluids – Chemicals to make Ag nanofluid in various concentrations.

For Determination Of• Young’s Modulus,• Ultrasonic Frequency Velocity

Non-Destructive Testing of Material is an important part of Engineering Education as it gives information without deformation in the shape and size of the material. One of the NDT techniques, Piezoelectric Technique is widely used for the measurement of composition dependent properties such as ultrasonic velocity, compressibility, elastic constant, Young’s modulus and Bulk modulus. Its suitability for metals, plastics, polymers and crystals etc makes it versatile tool for Engineering Physics, Material Science and Polymer Science. This low cost NDT apparatus is being used in several I.I.T.s/Universities/Engineering Colleges for laboratory experiments and Research work. 

In this technique the specimen is cemented to a quartz rod of identical cross section and resonant frequency (fc) of the composite system is determined using the apparatus. The resonant frequency of the quartz rod (fq) is also determined. From the knowledge of (fq), (fc) and the masses of the quartz (mq) and the specimen (ms), the resonant frequency of the specimen fs is evaluated using the relation 

ƒS =ƒC  + mq/mc   ( ƒcq)

Using the value of ƒS  , the length of the specimen (L) and the density of the specimen, the velocity of the ultrasonic waves in the specimen (v ) and compressibility (βad) can be calculated using relations 

V=2. ƒS . L
βad=1/P.V2 

where P is density of specimen . 

Young''s Modulus of specimen is calculated using relation 

r=4. ƒS. L2.P

INSTRUMENT: It consists of Piezoelectric Oscillator, power supply, quartz rod, holder, quartz rod with sample, connecting cables and R.F. meter.ACCESSORY: Any general purpose C.R.O.(not supplied with the instrument).

A dielectric is a material having low electrical conductivity in comparison to that of a metal. It is characterized by its dielectric constant. Dielectric constant is measured as the ratio of the capacitance C of an electrical condenser filled with the dielectric to the capacitance C0 of the evacuated condenser i.e.

ε = C/C0

Knowledge of the dielectric constant is of interest particularly to the Physicists and Engineers. A simple experimental set up is designed to measure the dielectric constant of solid samples in both range- LOW HIGH.

The experimental set-up consists of :i) Main Unit having audio oscillator (1 KHz), digital voltmeter (0 – 9.99 V dc), standard capacitance and electronic circuitry.ii) Dielectric Cells: 75 mm Gold plated brass discs (1 set) and 25 mm Gold plated brass discs (1 set).iii) Samples : Low Range : Glass, Backelite Hi Range : PZT DISC
