description: Purpose of work: selection of nozzle design, satisfying the requirements for the pressure at the inlet to the calculation area and the angle of span. Main tasks of the work: ï­ Determination of water pressure characteristics of the currently available nozzle. ï­ Determination of the dependence of the pressure drop on the nozzle design developed during this numerical work. ï­ Determination of the dependence of the half-solution angle on the nozzle design developed in the course of this numerical work. The finite volume method is used to perform the computations. The volume of fluid method is used to take into account the peculiarities of multiphase media calculations. As a result of calculations for each case the dependences of total pressure losses at the inlet boundary are determined, and also dependences of the exit jet half-angle on such parameters as: ï­ Nozzle design; ï­ Nozzle orifice dimensions; ï­ Location of orifices on the nozzle; ï­ Height of shields in the inner part of the nozzle. As a result of the work performed, a nozzle is developed, the design of which meets the initial requirements for the pressure at the inlet to the design area and the half-angle size. The influence of the nozzle elements on the flow-pressure characteristics is described.
