Abstract

We present a description of the motion of the extinguishing agent in flow path of water-foam nozzle in order to optimize its geometrical parameters by finite element method. Shows the general structure of the project, defined a computational domain and formulated boundary conditions of numerical simulation. Determined and analyzed the flow characteristics of the extinguishing agent in flow path of water-foam nozzle by which we can conclude the appearance of cavitation process and the extent of his influence. Offered the possible ways to improve the characteristics of water-foam nozzle.
