A new model is derived (and the corresponding numerical algorithm developed) to describe the temperature field of a suddenly exposed droplet experiencing moisture condensation from air‐steam mixture. This model is then compared with the predictions of two simpler models. Experiments done over a wide range of air‐steam concentrations, drop sizes and gas phase velocities show that the combined heat and mass transfer model incorporating partial internal mixing accurately predicts the temperature responses of the droplets.
