Reaction Zone Structure of Gaseous Hydrogen Chloride Jets Submerged in Aqueous Ammonia Solutions.
Abstract
A theoretical investigation of the structure of a turbulent, gaseous, reacting hydrogen chloride jet submerged in an aqueous ammonia bath was conducted. This particular combination of reactants has been found to produce a highly dynamic, rapidly fluctuating plume in experimental studies. A model for predicting the penetration length, temperature, and break off point of the plume was developed. The approach used employs the k-epsilon-g turbulence model, the locally homogeneous two-phase flow approximation, and a clipped Gaussian probability function for the square of the mixture fraction fluctuations. The model was evaluated using data obtained from high speed motion picture studies of periodic reacting hydrogen chloride jets discharging into an aqueous ammonia solution. The data was taken from experiments conducted at Argonne National Laboratory. The predictions for the temperature of the reaction zone and the total penetration length of the plume correlate well with experimental data. The hypothesis regarding the break off point of the plume provides quantitative estimates of the break off location in this test case, but further study in the area of periodic, reacting jets is desirable.
