Abstract:

We present a physical-mathematical model for describing the evolution of a cloud of toxic liquid propellant emitted in the emergency case of crashes and/or stage separation. The model developed takes into account the polydisperse composition of droplets, instability of their motion, and the prevailing wind. This model accounts for the process of droplet heating and freezing in different atmospheric layers, the phase changes, aerodynamic splitting, and turbulent diffusion. Some results calculated for a typical liquid propellant components are presented.
