Abstract
The Taylor Analogy Breakup (TAB) model is widely used to predict droplet deformation and breakup in spray simulations. It has four constants, which are usually varied to match simulation results with experimental results. These constants are coupled through the equations arising from the TAB model constraints and experimental constraints, making it difficult to guess the impact of their variation on the TAB model outcomes. In the present study, we vary these constants in a range allowed by these constraints and study the impact of their variation on the TAB model outcomes such as the prediction of droplet deformation, breakup time, the velocity of the product droplets normal to the path of the parent droplet and, Sauter mean radius. We also suggest a change in the energy equation, which is used to calculate the Sauter mean radius. This study enables the reader to gauge the significance of each of the four constants and gives a ready-made reference for choosing their appropriate values for matching the simulation output with that of the experiment.
