Study of thermodynamic, transport and volumetric properties of nanofluids containing ZrO₂ nanoparticles in polypropylene glycol, polyvinyl pyrrolidone and water.

ABSTRACT: Zirconium dioxide (ZrO₂) nanofluids are used in cooling systems, solar energy, and heat exchangers, offering improved heat transfer and efficiency across a wide temperature range. The aim of this work was to study the influence of polypropylene glycol (PPG) and polyvinyl pyrrolidone (PVP) and aqueous solutions of them as a base fluid on stability, volumetric properties, and viscosity of nanofluids containing Zirconium oxide (ZrO₂) nanoparticles. The stability of these nanofluids has been confirmed using UV-Vis spectroscopy, and the particle size distribution of the systems using dynamic light scattering (DLS). Among these systems ZrO₂-PPG and ZrO₂-H₂O-PVP30% have appropriate stability. The density, speed of sound and viscosity of these
