Secondary Atomization on Two-Phase Shock Wave Structure
The use of sprays in liquid and gas flows covers a wide range of applications . The efficiency of such multiphase systems to mitigate the devastating effects of blast waves which are issued from explosion is well known . Indeed during shock loading, the water mist is subjected to aerodynamic forces from the carrier phase, which leads to a secondary atomization  of its individual liquid components. This induces a drastic increase of interfacial surface as well as interphase exchanges. Two-phase shock wave is known to show a long-time self-similarity behavior. The aim of this work is to investigate the transient pressure build-up due to secondary atomization and to confront the results from shock tube experiments with numerical modeling.
