| Abstract: | A numerical computation is presented for the reaction zone structure of a turbulent, gaseous, reacting hydrogen chloride jet submerged in an aqueous ammonia bath. The state relationships as a function of mixture fraction are generated from the chemical equilibrium calculations. Used in the approach are the locally homogeneous flow approximation (LHF), the k-f4- g turbulence model, a clipped Gaussian probability function for the mixture fraction, and Favre-averaged transport equations. Predictions are made for the void fraction, temperature, penetration length, and concentration profiles of the plume. The calculated results including plume penetration lengths and void fraction profiles are found to be in good agreement with the experimental data. |
