Abstract:
Thermal radiation simulation of nuclear events have been achieved by a variety of processes due to the ban on above ground nuclear tests. Each thermal radiation simulator is unique in its ability and limitations. The simulator type addressed within is the liquid oxygen/aluminum powder combustion Thermal Radiation Simulator (TRS). Where a square thermal pulse is desired, the ensuing flux vs. time record is ordinarily a rough approximation. Time delays brought on by valve actuations and turbulence in the flame wall all serve to distort the desired perfect rectangular pulse. The result is to generate disagreement as to what the actual average flux level is and the length of pulse duration. Four different analytical schemes to determine average flux and pulse duration are presented and compared. Advantages and restrictions are discussed.
