Propagation Characteristics of Laser Supported Combustion Waves in Flowing Media
Abstract
The basic research objectives are: 1. Perform stability analyses of LSC waves in which molecular absorption is the primary absorption mechanism. 2. Investigate the feasibility of using circumferentially uniform radiation to sustain an LSC wave. 3. Look for absorptivity characteristics and energy deposition patterns which will yield improved wall cooling characteristics, increased radiation trapping and resultant reductions in energy losses. 4. Identify important parameters in ignition transients and assess this effect on a propulsive system, and 5. Assess the general effects of variations in the wavelength of laser radiation (from 10.6 microns) on the above and related parameters. As an initial step in understanding the behavior of laser supported plasmas in pure hydrogen, a computer code has been written to determine the high temperature properties of equilibrium hydrogen. Specific properties which are computed include the absorptivity, equilibrium concentrations, enthalpy, internal energy, viscosity and thermal conductivity. Some one-dimensional laser supported plasma calculations are being performed using these property variations. (jhd)
