Numerical Simulation of Water Mist Suppression of Tunnel-fire Scenarios
Water-mist fire suppression systems offer a number of potential advantages over conventional sprinkler systems. A water-mist system uses very fine droplets of around 50μm diameter, which results in entirely different behaviour. In particular the water-mist remains suspended in air for long periods, and is influenced by the airflows caused by the fire and the general ventilation regime. In order...
متن کاملA Multi-Physics Simulation Model Based on Finite Element Method for the Multi-Layer Switched Reluctance Motor
Using ANSYS finite element (FE) package, a multi-physics simulation model based on finite element method (FEM) is introduced for the multi-layer switched reluctance motor (SRM) in the present paper. The simulation model is created totally in ANSYS parametric design language (APDL) as a parametric model usable for various conventional types of this motor and it is included electromagnetic, therm...
متن کاملdiesel engine simulation using a multi zone model and chemical kinetics mechanism
main purpose of current study is development of a new multi zone model for direct injection diesel engines. zone configuration is based on conical shape of spray. siebers’s correlation is used for spray cone angle calculation. experimental data are used for calculation of fuel inlet mass flow rate. fuel diffusion in different zones is calculated using fick’s law. a chemical kinetics mechanism c...
متن کاملA Two-zone fire growth and smoke movement model for multi-compartment buildings
A fire growth and smoke movement model for a multi-compartment building has been developed at the National Research Council of Canada. This development is primarily intended to help evaluate the risk from fires in buildings. This paper presents the related physical models, numerical methods, and some verification examples. The 2-zone ordinary differential equations (ODEs) are derived for the co...
متن کاملNumerical simulation of water entry of tunnel cross section with different deadrise angles and tunnel radiuses
This study deals with the numerical modeling of symmetrical water entry of tunneled sections. In this study, firstly, the water entry problem of a wedge section without tunnel in four different deadrise angles was numerically modeled. The obtained results related to the pressure distribution on these sections and the maximum pressure have been compared with the experiment results. In the next s...
