ENTRAINMENT AND EXPANSION CONTROLLED FIREBALL RISE

Abstract

This paper reports on a detailed analysis of the buoyant rise of fireballs in the earth's atmosphere. Formulae for the rise velocity and height, and the density, mass, radius and expansion velocity of the fireball are given. The computation of fireball temperature is discussed in detail; no explicit expression could be given because of the nature of the problem. The assumptions and simplifications on which the analysis rests are summarized in a separate section. In order to facilitate applications, a complete numerical example is given. Frequently used quantities are calculated and presented in graphical and tabular form.
