Abstract: One-dimensional radiation hydrodynamics equations with spherical symmetry are used to study early development of fireball front and case shocks in strong explosion.Numerical method for radiation transport equations is established.The calculation results agree well with Brode's.Early formation of fireball front and case shocks in strong explosion at different yield,density in explosion zone and altitude are simulated numerically.Calculation results are analyzed.

Key words: fireball of strong explosion, radiation hydrodynamics, numerical simulation
