Two-Phase Media Model of Shock Compression with Chemical Reaction
Shock synthesis of materials from powder mixtures is a potentially important method for producing new substances with unique properties. In addition to the potential practical benefits of shock synthesis technology, researchers are attracted to the subject because mechanisms of chemical reaction under shock loading are of independent scientific interest. A valuable feature of chemical reactions in which products are synthesized from a mixture of powdered reactants is that the reaction rate and/or product yield is enhanced if shear deformation is imposed concurrently with the application of the high pressure and temperature required for the reactions to proceed. This makes shock compression an ideal means of realizing these reactions . Theoretical investigations in this field have been directed toward the construction of numerical models that are sufficiently detailed to capture the essential aspects of the behavior of multiconstituent media . Particular aspects of the problem of shock-induced chemical reaction in powder mixtures makes further improvement of these models necessary. In particular, it is important to take into account not only mass and energy exchange during the chemical reaction but also differing velocities and temperatures of the constituents of the reacting mixture.
