A study of the interactions of chemical kinetics, relaxation processes, and low-speed fluid mechanics is presented for the deflagration of gaseous carbon disulfide and oxygen under conditions for which laser action has been demonstrated. A four-reaction branching chain reaction mechanism is deduced from experimental evidence and reaction rates to represent the chemical kinetics of CS/sub 2//O/sub 2/ combustion. This chain mechanism is used to explain some explosion phenomena and to obtain the initial conditions and initial chemical kinetics expected for the different types of CS/sub 2//O/sub 2/ chemical lasers. The dynamics of chemical population and relaxation, including selective depopulation, of the vibrational levels of CO are discussed. Three analytical methods are employed to solve the premixed laminar flame problem for the CS/sub 2//O/sub 2/ flame. Details are given for the multi-slit injector whose design allows complete control over mixing. Results for this burner and premixed configuration burners are discussed. CO emission spectra were taken from CS/sub 2//O/sub 2/ flames and the relative vibrational populations determined. (GRA)
