Sažetak
The paper proposes an iterative numerical algorithm developed for determining optimal distribution of nozzle opening areas along the diffuser of a submarine outfall. For the given flow geometry, the proposed nu¬merical procedure results in a distribution of nozzle opening areas needed for ensuring a uniform outlet flow and the required initial dilution in the near field. The procedure also facilitates the determination of nozzle opening areas necessary for ensuring uneven distribution of the previously given flow. The unknown values of the nozzle opening areas and outlet velocities are obtained simultaneously by means of two interactive iterative loops. For the given values of the outlet velocities, nozzle areas and constitutive equations for pressure loss are calculated in the outer iterative loop. The obtained values are then used in the inner iterative loop where the next approximate value of the outlet velocities is determined by the Newton-Raphson method. The procedure is repeated until both convergence criteria are met. In addition to a theoretical overview and the associated numerical algorithm, several numerical examples are also presented.
