RADIATIVE HEAT FLUXES IN THE VICINITY OF OXYGEN-HYDROGEN FIREBALLS

The paper describes the results of calculation of spectral and integra l radiative heat fluxes in the vicinity of fireballs formed as a resul t of explosions of rockets fired with oxygen-kerosene fuel of the tota l mass of 400 t. Two numerical methods are used in the calculations, n amely, the P-1 approximation of the spherical harmonics method and the Monte Carlo method. It is shown that distances on the order of 1 km f rom the explosion site are dangerous from the standpoint of radiation heat load.
