Lanthanum Oxide-Barium Oxide Nanofluid with Enhanced Thermal Engineering Application

Therminol is a thermally stable heat transfer fluid with a high boiling point and low vapor pressure. Boosting the heat conductivity of therminol is a potential way for increasing the efficacy of therminol-based systems. It will improve performance while compensating for the drawback of poor thermal system performance. Nanofluids are believed to be more efficient than traditional fluids. In this study, experiments were conducted to examine the thermal properties of therminol, including thermal conductivity and viscosity, when a Lanthanum Oxide-Barium Oxide (LaO-BaO) nanocomposite was dispersed in it. LaO-BaO nanocomposite was created via chemical co-precipitation route. Structural and optical characteristics of the nanosamples were investigated using X-ray diffraction (XRD) and UV-visible spectroscopy. Therminol was used as the base fluid in the fabrication of LaO-BaO-based nanofluid. When compared to the base fluid, therminol; the nanofluid exhibits a considerable shift in heat conductivity and viscosity. To assess the potential changes in the thermal conductivity of the base fluid, thorough tests were carried out at various temperatures and weight percentages of LaO-BaO nanocomposites. The results suggest that LaO-BaO nanofluids are a superior substitute against other regular fluids in heat transfer applications.
