Abstract
A numerical method has been developed to calculate low Mach number and reacting flows in general and the burning and vaporization of a hydrocarbon droplet in particular. The method is time accurate and it makes use of the continuity equation to form a pressure correction. The basic transport equations have been given in finite volume form, and a predictor/corrector algorithm has been employed. The continuty equation and the pressure correction step have been solved to high numerical accuracy with the use of a direct solver technique, which also has the advantage of improved efficiency. The physical problem of the burning and vaporization of a high molecular weight hydrocarbon droplet is a very difficult one due to the very large temperature and density gradients in the flow, and also due to the complicated flow structures which develop during a droplet's lifetime. The methods used in this research have successfully solved these problems, and a detailed history of the droplet has been calculated and studied.
