Shock Wave Modelling and the Hull Computer Code Formation of Mach Stems.

摘要

The HULL code has been modified to run and an Australian computer system (CSIRO Cyber 7600) so that an examination of its capabilities could be undertaken. In particular HULL was used to simulate the collision of a travelling shock wave with an oblique ramp set up within a shock tube. The resultant Mach Stem formation and growth and the triple point trajectory were analysed and their validity verified using the Rankine-Hugoniot relationships across the shock front and the Whitham theory on shock ave diffraction at concave corners.
