Pulse echo comparison method with FSUPER to measure velocity dispersion in n-tetradecane in water emulsions

摘要

In this paper, a pulse-echo comparison method for measuring ultrasound velocity dispersion in n-tetradecane emulsions is presented. The method was based on an existing device but used a new measurement strategy. Ultrasound velocity in n-tetradecane in water emulsions was measured around the frequency range 1-14 MHz. The results were compared with theoretical prediction. The method is capable of development as an on-line real time method to characterize food emulsions. (C) 2002 Elsevier Science B.V.
