Properties of actual and numerical shock and blast wave phenomena

Considerable progress was made in the areas of application of the random-choice method to explosion and implosion dynamics (flows with changes in area and detonation) and weak spherical shock-wave transitions (flows with viscosity, heat conduction), and vibrational excitation - a first). Some progress was also made in applying the fluid-in-cell technique to oblique-shock-wave reflections (OSWR). The method looks promising. A great deal of experimental and analytical work was achieved on OSWR in air and SF6. The dusty-gas shock tube is being assembled. Two analytical papers on dusty-gas shock-tube flows have appeared in the Proceedings of the Royal Society of London with AFOSR support, as well as other papers and UTIAS reports.
