Analysis of the Thermal Response of a Hydro-Carbon Fuel when Subjected to a High Intensity Laser.

Abstract

An investigation was performed on laser-fuel interactions. The investigation included an analysis of laser ignition modes, ignition criteria, and the laser requirements for vapor ignition. The modes investigated were the wall heating mode for heating due to heat transfer from a laser irradiated plate and the direct heating mode for heating due to direct laser impingment on the fuel vapor. A computer programed mathematical model for one-dimensional heat transfer was used to determine the thermal response in a metal plate backed by liquid fuel or fuel vapor, and the fluid heating rate. Aluminum and titanium were considered. The investigation shows that in general, the laser has the capability of causing fuel fire or explosion. (Modified author abstract)
