A modified version of the Hartmann-type stem and cavity air jet acoustic generator coupled with a twin-fluid air-assist atomizer has been used to form a unique practical device for atomization, emulsification and combustion applications. The effects of acoustic and fluid dynamic fields on the atomization parameters have been investigated theoretically. These results have been employed to evolve a step-by-step procedure for designing the important parameters of the twin-fluid acoustic device. Detailed experimental work has been performed to study the effect of various flow and fluid properties on the mean drop size of the spray. The results have been correlated to arrive at a semiempirical equation for estimating the Sauter mean diameter of sprays from the acoustic device, applicable in the range of fluid properties and test conditions employed. Incorporation of the acoustic device into a practical combustion chamber has proved to be successful.13;
