摘要：
In this paper, we present the results of laboratory tests conducted to investigate ultrasonically enhanced flow rate using specially designed and fabricated equipment. The influencing factors alpha(i) are verified to investigate the effect of ultrasound on a soil matrix and a flowing liquid. The conditions tested were soil type, temperature and ultrasonic energy. The test results indicate that ultrasound enhances flow rate significantly. The degree of enhancement and the values of influencing factors, alpha(i), however, vary with test conditions.
