“…A large amount of energy in the form of temperature and pressure is released whenever the two gases react. Basov et al (1969) considered that the reaction between H 2 and F 2 involves a branched chain mechanism. According to Sullivan et al (1975), the H 2 -F 2 reaction is a chain type in which free radicals help in propagation of reaction steps.…”

The authors studied the reaction between H 2 and F 2 , which is highly exothermic in nature, experimentally and computationally. The reaction was carried out in a tubular reactor. Flow rates of H 2 and the N 2 -F 2 mixture were varied and the authors report the results in terms of temperature, velocity, and concentration at different locations of the reactor. Numerical simulations were carried out and the temperature profiles predicted by these simulations are compared with the experimental ones. A good match is observed between the two. It has been seen that the reaction temperature is different from what is reported by Wilson et al. (1951), when fluorine is premixed with inert gas like nitrogen. It is also observed that the flame due to the reaction between hydrogen and fluorine is formed in front of the fluorine feed nozzle. The investigation results are useful for the process design of an H 2 -F 2 reactor.

The time-resolved spectral output of pulsed DF and DF-CO2 chemical lasers initiated by fast electrical pulses has been investigated. Short-pulse electrical initiation of the D2+F2 mixture in the high-pressure DF-CO2 laser results in prompt laser emission from both DF and CO2 molecules in addition to the usual more energetic, but delayed, CO2 emission. Studies of the time correlation of the vibrational-rotational transitions observed in the DF and DF-CO2 systems provide evidence that the transfer of energy from DF (v?4) to CO2 involves transitions in which the rotational level change in DF is greater than one.
