Numerical study of thermal destruction of the "Chelyabinsk" meteorite when entering the Earths atmosphere

Abstract

A mathematical model for the numerical study of thermal destruction of the "Chelyabinsk" meteorite when entering the Earths atmosphere is presented in the article. The study was conducted in the framework of an integrated approach, including the calculation of the meteorite trajectory associated with the physical processes connected with the meteorite motion. Together with the trajectory the flow field and radiation-convective heattransfer were determined as well as warming and destruction of the meteorite under the influence of the calculated heat load. An integrated approach allows to determine the trajectories of space objects more precisely, predict the area of their fall and destruction.
