| Summary: | Title screen The results of incorporating two recently developed models of composite droplet puffing/micro-explosion in a customised version of ANSYS Fluent via UDFs (User-Defined Functions) are presented. Both models, assuming that a water subdroplet is located in the centre of a stationary spherical fuel droplet, apply analytical solutions to the temperature equation within the droplet. The first model, known as the analytical model, leads to the analytical expression for the distribution of temperature in the droplet, which is valid at all times until the onset of puffing/micro-explosion. The second model, known as the analytical–numerical model, leads to a similar expression, but this expression is valid only during a short timestep. It is implemented within a numerical code where the prediction of the model at the end of a timestep is used as the initial condition for the next timestep with updated values of thermophysical parameters. The customised ANSYS Fluent version with the new analytical–numerical model is verified by comparing its results with the predictions of the in-house code. The predictions of the latter code were earlier verified by comparing the predictions of the analytical–numerical model and those of the purely numerical model. Reasonably good agreement between predicted and observed (both in-house and published) times to puffing/micro-explosion is demonstrated, especially at small initial droplet radii and high temperatures Текстовый файл AM_Agreement |
