A Comparative Study of Nanofluids for Tuneable Filter Operation
Nanofluids are engineered colloidal suspensions of nanoparticles in a base fluid. The nanoparticles used in nanofluids are typically made of metals, oxides, carbides, or carbon nanotubes. Common base fluids include water, ethylene glycol and oil. Recent reports have revealed the possibility of developing fluid filters deviating from the conventional modelling and design techniques. Mixtures of nanoparticles in liquids can be used as an alternative to conventional optical filters. In this paper the optical transmittance spectrum of hematite, silicon, gadolinium and titanium nitride with the variation of volume fraction, thickness of liquid layer and particle diameter will be analysed using simulation results for the determination of feasibility of their use in tuneable optical filter operation.
