Determining the radius of the air vortex during the laminar flow of a liquid in a centrifugal atomizer

In existing theories of centrifugal atomizers, such as that of Abramovich 1], in order to determine the radius r₀ of the air vortex the conditions of the maximum rate of flow or some other extremal principle are conventionally employed. In this paper the radius of the air vortex will be determined from the equations of motion of a viscous incompressible liquid.Translated from Zhurnal Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 3, pp. 54–57, May–June, 1976.
