Effect of Ultrasound on Rate of Flow through Porous Media

Abstract

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 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, i , however, vary with test conditions.

Ultrasonically Enhanced Diesel Removal from Soil

“…The effect of ultrasound on flow rate through soils was reported by Kim et al 1) However, available information about the effects of ultrasound on the extraction of contaminants from porous media is limited and piecemeal. Iovenitti et al 2) reported a 6 -26% improvement in surrogate contaminant extraction using ultrasound.…”
