    Abstract
  • The temporal and spatial distribution of explosion cloud in diffused experiment is analyzed and studied. Cloud diffusion in the atmosphere is simulated by fluid dynamics software. Initial conditions of the cloud are optimized by calculation and experimental program. Cloud movement process rising in vortex flow and flow parameters such as density, velocity, temperature and pressure are obtained from the simulation. The formation mechanism of the explosive mushrooms cloud and the vortex movement in gravity caused by different buoyancy force are discussed and analyzed.
