Abstract

An ultrasonic fluid processing method is provided for cavitation and processing a first fluid with a second fluid in a sonication or cavitation zone. The method is useful for preparation of emulsions for chemical and pharmaceutical applications, to gasify liquids for purification, for chemical reactions, to accelerate chemical and physical reactions, and to suspend fine particles. The method includes the steps of, forming a vibration element having an axis and with an adjacent sonication or cavitation zone, enclosing the element and zone in a sealed cavity having a first fluid passage, forming a second fluid passage coaxially with the vibration element and disposed adjacent to the sonication zone, and forming a third fluid passage coaxially with the vibration element and disposed adjacent to the sonication zone. With this method, problems with the control of proportions and amounts and uniformity of parts of fluids being mixed or processed are avoided.
