Enhancement of Thermal and Acoustical Properties of Hybrid Nano Fluid

Abstract

In this paper, ash from agriculture waste i.e., sugarcane bagasse was used in the synthesis of silica. Nanoparticles were followed by using leaching and acid treatment. The required ash from agriculture waste (sugarcane bagasse) are subjected to sintered at 700℃ at 5hours in order to reduce the residuals from the ash. The obtained powder was treatedwith1M of NaOH for leaching and then acid treatment with 0.5M H2SO4 to precipitate pure SiO2 Nanoparticles powder. The synthesized silica were charecterized by XRD,FTIR). Using neem leaves extract, extraction of silver (Ag) nanoparticles was obtained. These plant extract (neem leaves) can be act as capping agent and reducing agent. Charecterization were done for this process i.e., XRD and FT-IR. This procedure requires 15min for conversion of silver ions to silver nanoparticles, without any harmful chemicals. Nanofluids were prepared by synthesized Ag-SiO2 nanoparticle dispersed into water i.e.,base fluid using ultrasonication method. These nanoparticles were characterized by zeta potential, FT-IR and Ultrasonic Inferometer. Nanofluid with volume fraction of 0.04% and 0.06% at different temperature are using for the measurement of ultrasonic velocity(v),then predict the adiabatic compressibility(β),intermolecular free length(Lf), Accoustical Impedence(Z) and thermal conductivity(k) of nanofluids. This experiment mainly concluded that agricultural wastages, converted into a valuable product, reducing environmental impact of disposal problems. Increase the thermal conductivity of metal by adding metal oxides for nanofluids.
