Besides application of high-speed temperature measuring instrumentation, a search was made for a digital computer program that could be adapted to the problem. This resulted in the evaluation of the KO code developed by the U. of Cal. Radiation Laboratory. This code uses a numerical differencing method with injection of a Q-term of artificial viscosity whenever an incipient shock condition develops. The addition of the Q-term in appropriate amounts prevents a discontinuity so that the computer program can then handle the shock condition and determine when and where it will develop as well.
