- Abstract
- This research investigation is concerned with detailed calculations of the unsteady heating and vaporization of liquid droplets for Reynolds numbers between 10 and 100 and Peclet numbers between 100 and 2000. The calculations are based on a numerical solution of the Navier-Stokes equations and the problem's thermodynamic and transport properties have been chosen to be characteristic of those of a heavy fuel such as dodecane. One of the major goals of this study is to provide detailed modeling of the complex processes occuring so that simple models can be evaluated and developed. The results of this study show that there is a large number of transport regions possible which depend strongly on the Reynolds, Prandtl, and Peclet numbers of the problem. Also, for the parameter range studied, there does not seem to be one simple model which will descibe adequately all of the transport processes occuring during droplet heating and vaporization.
