Modelling in the design of a flow-through ultrasonic separator
Modelling in the design of a flow-through ultrasonic separator
This paper describes the design and testing of a flow-through ultrasonic separation device that allows the concentration of particles within a fluid. The device operates without the use of an acoustically transparent element. Three models are used to examine the behaviour of the cell, dealing with acoustic–particle interaction, electro-acoustic characteristics, and fluid flow. The device is able to concentrate up to 84% of the 60 ?m sand particles in the ‘dirty’ stream, 13% in the intermediate stream and 3% in the ‘clean’ stream. Flow rates of up to 20 l h?1 (equating to an inlet velocity of 10?2 m s?1) have been used with an electrical power input of up to 50 W (10 kW m?1)

Abstract
This paper describes the design and testing of a flow-through ultrasonic separation device that allows the concentration of particles within a fluid. The device operates without the use of an acoustically transparent element. Three models are used to examine the behaviour of the cell, dealing with acoustic–particle interaction, electro-acoustic characteristics, and fluid flow. The device is able to concentrate up to 84% of the 60 ?m sand particles in the ‘dirty’ stream, 13% in the intermediate stream and 3% in the ‘clean’ stream. Flow rates of up to 20 l h?1 (equating to an inlet velocity of 10?2 m s?1) have been used with an electrical power input of up to 50 W (10 kW m?1)
