An experimental investigation followed by some theoretical considerations suggests that the triple point of a three-shock confluence behaves as a 'hot spot'. Numerical calculations using the HULL code, which was developed by the U.S. Air Force Weapons Laboratory and modified by 'S-Cubed' have provided supporting evidence for hot-spot behavior near the triple point. Furthermore, the numerical calculations also show a spike in the internal energy, the pressure, and the density near the triple point.
