Abstract
In this study, the background gas of the droplet vaporization was concerned and simulated numerically using ANSYS fluent code. The new type, engine-like, condition of high pressure chamber and high temperature environment was considered to conduct experiment on kerosene droplet evaporation. 2D geometry of domain simulation was discretized in the very fine quadrilateral meshes. The numerical approach was solved using implicit scheme of compressible gas solver (density based). Temperature dependent properties of air are expressed for gas material properties. As the study concerning on high pressure condition the equation state of Peng-Robinson was expressed in simulation. Governing equations of mass, momentum and energy were solved by the second order upwind for flow, turbulent kinetic energy and turbulent dissipation rate. Standard k-ε model was used to solve turbulence flow in the spatial discretization. The effects of the non-ideal gas phase behavior were found to be important for prediction background gas of droplet vaporization especially in high pressure environment. It can be concluded that we can predict the environment of high temperature and high pressure condition, however the quantitative measurement of droplet evaporation is still facing problem on physical devices. The environmental conditions has significant effect on droplet behavior inside the chamber.
