ABSTRACT:
In this present study, the work deals with investigating the effects of bi-metallic nanoparticle in the base fluid (water). Copper nanoparticles were prepared by size control method and alumina nanoparticles (Al2O3) were purchased. Then by using the above nanoparticles subsequent nanofluids were prepared by two step method for the preparation of nanofluid. Uv Spectroscopy, X- Ray diffraction (XRD) and Scanning electron microscope (SEM) were done to characterize the nanoparticle. Bi-metallic nanofluid of Cu (core)/Al2O3 (shell) structure was synthesized and its thermal conductivity was measured. Then the experimental value of thermal conductivity was compared along with theoretical value, which is determined with the help of “Maxwell model for thermal conductivity for solid – liquid mixture” for low solid concentration. After preparation of nanofluid they were measured using KD2 PRO thermal conductivity analysis devices and for Copper Nanofluid the thermal conductivity was increased by 7% than the basefluid and for alumina, thermal conductivity was increased by 10% than basefluid. And Bi – metallic nanofluid, thermal conductivity was measured with the help of KD2PRO and there was 22% increase in the thermal conductivity than the base fluid.
