A pool model has been developed to predict the evaporation of a liquid fuel from a surface in response to a fire. The model exists in the Fuego, Kameleon, and Vulcan fire codes. The model solves for the mass evolution based on what are thought to be the dominant input boundary conditions. Some empirical assumptions are made to predict the behavior of lower order physics. The performance of the model is evaluated by comparing predicted results with measurements for a variety of test cases in Fuego. Qualitative performance of the model is found to be reasonable. The model is found to yield quantitative results of mixed accuracy, suggesting the worth of considering improvements to the model. Evidence from the study helps indicate the future direction for improving this class of model.
