There exist a large number of models of droplet heating and vaporization rates with different complexities and computational costs. This paper reviews briefly those which are currently or have a good potential to be used for efficient CFD (computational fluid dynamics) simulation, e.g. commercial CFD packages such as Fluent. All the models discussed in this paper are simple and CFD efficient, i.e., incorporation of them would not add substantial computational cost. However, many assumptions (e.g. infinite thermal conductivity in the droplet) are made for these models, and the models may have limited accuracy if the assumptions made are not satisfied.
