Abstract:Computational fluid dynamics(CFD) method was implemented to study the fine water mist in the fire protection of manned spacecraft.The sheet atomization model of pressure-swirl atomizer and the motion model of mist particle were built.Discrete phase model(DPM) was used to simulate the characteristic of fine water mist field in microgravity.The atomization graph,velocity and the particle size distribution of fine water mist in microgravity was simulated.Results have shown that the characteristic of fine water...
