SPRAY heating and vaporization is a common feature in numerous processes, such as spray combustion and spray drying. In the first, temperatures are high enough to make radiative heat transfer important. However, the existing models for single-droplet vaporization and combustion do not consider radiation at all (Faeth, 1 Law, 2 Sirignano, 3 and Rangel4). In the framework of spray combustion modeling, the singledroplet vaporization model should include the radiation absorption inside the droplet, whereas, the whole combustor simulation should be responsible for taking into account the radiative heat exchange among surfaces and volume elements. The simplified single-droplet models used in global combustor simulations (eg, Abramzon and Sirignano, 5 Tong and Sirignano6) should then be extended to include the internal radiation absorption by the liquid fuel. The heating and vaporization of a stagnant water droplet irradiated by a laser beam has been analyzed by Park and
