Estimation of the numerical values of the evaporation constants of water droplets moving in a high-temperature gas flow

As the result of the experiments on liquid (water) drop movement in a high temperature (above 1000 K) gas flow performed using the optical diagnostics of the two-phase and heterogeneous gas-vapor-liquid mixtures, the integral characteristics (the mass rates) of the drop evaporation process are determined. From the experimental values of these characteristics, the constants of the liquid drop evaporation in a high-pressure gas medium on the basis of the known heat and mass transfer models are calculated.
