물-피마자유 경계에서의 주입 온도의 관찰

Abstract

Properties of acousitc propagation are characterized by an acoustic impedance of the medium, which is expressed as a product of the sound speed and the density of the medium. When acoustic signal is incident on the boundary between two different media, the acoustic reflection at the interface depends on the difference between the acoustic impedances of two media. Previous studies on the reflection at a bundary formed by two different media have mainly focused on the investigation of reflection properties as a function of grazing angle. In this study, we investigate on the reflection loss as a function of temperature between water and castor oil. In conclusion, the ‘temperature of intromission’ is observed inthe measurements, which is compared to the theretical model predictions.
