Abstract
Developed a method of design calculation jet-centrifugal gas-liquid duplex fuel nozzle with internal mixing of the generalized structural scheme. Expressions are obtained for determining the coefficient of discharge of the centrifugal fuel nozzle, taking into account the real flow of the fuel components. To a minimum diameter nozzle at the outlet duplex fuel nozzle, which provides independent from each other work and the calculation of internal and external contours. This allows the required accuracy for practical purposes to calculate all required parameters of the projected duplex fuel nozzle.
