Abstract

This thesis explores the sound speeds and derived thermodynamic properties of CO2 and NaCl water mixtures, R32 refrigerants, and toluene to address knowledge gaps in climate change research, carbon capture, alternative refrigerant development, and various industrial applications. Dual-path pulse-echo sensors were utilized to measure sound speeds for water mixtures, toluene, and R32, while a novel acoustic resonator was employed for R32 + CO2 mixtures, emphasizing the need for improved equation of state (EOS) models. The experimental sound speeds and derived thermodynamic properties can aid in optimizing industrial processes and promoting the development of sustainable technologies.
