Energy Release Estimation for Fragmenting Meteoroid

摘要

It is known that for the adequate interpretation of fireball observations it is necessary to take into account its fragmentation in the Earth's atmosphere. Various models for large cosmic body destruction in the atmosphere are known. Presented work continues our previous research on the fragmentation of fireballs. Proposing a model for the destruction of a fireball we also submit a model for the transition of its kinetic energy to thermal one. The meteoroid destruction under consideration is similar to the destruction of a solid body during an explosion. The kinetic energy of the moving particles of the crashing meteoric body transform into the thermal energy of the gas volume in which their motion occurs.
