Investigation of hydrodynamic processes of the automatic impulse extinguishing
Santrauka
The simple way to increase the extinguishing water surface area is to atomize water into fine drops. The smaller the drops are developed, the better use of the water properties can be implemented and less water is consumed in fire fighting. The main aim of the investigation is to develop approach to investigate hydrodynamic processes in the extinguishing device. The mathematical model of extinguishing device is presented, where the flow of fluid and gas and the interaction of liquid with the gas are taken into account. The/low of fluid in a hydraulic system is described by a system of equations of a hyperbolic type, which is solved by a characteristics method. An instance of the mathematical simulation of the activity extinguishing device is shown. The dependence of recoil force is obtained.
