High Temperature Chemical Kinetic Studies.
Abstract
The advantages of coupling gas dynamic principles and procedures to chemical kinetics investigations were demonstrated again by studies made during the report period. Two shock-tube techniques and various chemical diagnostics were used to develop a kinetic mechanism for the drastic reduction of nitric oxide pollutants by control of the levels of hydrocarbons and oxygen over a suitable temperature range. Also, a general procedure was formulated for writing computer codes for very complex kinetic systems. Parallel to these studies of reacting mixtures at high temperatures, research was continued on a novel method for measuring vibration - vibration - vibration and vibration - translation energy transfer rates at room temperature. These experiments are unique in that molecular states which cannot be directly pumped by infrared radiation can be populated by coherent raman excitation, so that direct measurement of transfer efficiencies from totally symmetric to dipolar states were made. Positive results were obtained for vibration - vibration rates from deuterium to carbon monoxide and to hydrogen chloride. (Author)
