Abstract
The near field of a blast wave generated by the detonation of a centrally ignited, spherical TNT charge is investigated via numerical simulation. The study focuses on the effects of the Rayleigh-Taylor and the Richtmyer-Meshkov instabilities on fluctuations in the pressure field. The numerical simulations are performed with a finite volume multi-fluid ALE-method on globally adapted grids, which stretch with the expanding blast wave. The paper describes the details of the applied methods and gives a survey on the results obtained.
