Turbulence Effects

A new approach to account for finite thermal conductivity, finite mass diffusivity and turbulence effects within atomizing liquid sprays at high pressure condition is presented in this paper. The finite conductivity model is based on a newly developed two-layer film theory, where the turbulence characteristics of the droplet are used to estimate the effective thermal conductivity [1]. The present paper extends the formulation to model the multi-component mass diffusivities within the droplet phase at high pressures but less than components critical pressures. An approximate solution to the quasi-steady energy equation was used to derive an explicit expression for the heat flux from the surrounding gas to the droplet–gas interface, with inter-diffusion of fuel vapor and the surrounding gas taken into account. The Peng-Robinson equation of state (EOS) is used for extension of the model to the high pressures. The latent heat of vaporization and fuel enthalpies are also corrected for high pressure. The model includes the non-ideal gas and liquid behavior, and variable thermo-transport properties including their dependence on pressure and temperature. For this study a mixture of decane and hexadecane fuel droplet was considered. Predictions of the high-pressure single droplet model are in good agreement with the available data in literature.

Evaporation Stage

A simplified set of equations is examined for the problem of droplet evaporation. The equations employ the Clausius-Clapeyron boundary condition for the surface fuel-vapor condensation, which is responsible for numerous interesting mathematical behaviors, including the existence of an initial condensation stage followed by the classical d2-evaporation stage. Numerical methods of analysis are used, in conjunction with asymptotic analysis of each stage: (I) condensation; (II) transition; (III) evaporation. Comparisons are made with previous experiments. A brief discussion is provided of effective droplet evaporation in partial condensation environments.
