Quantitative Evaluation of Ultrasonic Wave for Liquids and Glasses Materials Characterization

A Comprehensive Analysis of Ultrasonic Wave Propagation for Liquids and Glasses Materials Characterization

Abstract

Ultrasonic velocity measurements are highly useful for the investigation of molecular interactions and the structural behavior of molecules in liquids, liquid mixtures and solids. Ultrasonic study provides a wealth of information about the state of the liquid. This technique is frequently used because of their ability in characterizing the thermodynamic and physic-chemical behavior of liquid mixtures. Investigation of the physical properties of liquid mixtures with varying compositions gives valuable insight into the microscopic structure and nature of molecular interaction in liquid molecules. The relatively simple and inexpensive equipment for the generation and detection of ultrasonic waves and the nondestructive character of the small amplitude vibrations make ultrasonic wave propagation used for nondestructive inspection (NDI). Typical applications include the detection of internal flaws, the measurement of layer thicknesses of laminated structures and the evaluation to assess the extent of corrosion.
