- Description
- Evaporation of fuel droplets in a convective environment has significant applications in several energy systems for example internal combustion engine. Appropriate estimation of evaporation rate is critical in predicting performance of the system, which involves computation of the relevant heat and mass transfer terms. All of these terms are sensitive to the physical properties of the phases and affected by the transient variation of the corresponding phase temperature. In the present study, effects of temperature dependent thermo-physical properties of both liquid and gas phases on the evaporation behaviour of the droplet were investigated using a previously reported vaporization model (Nguyen et al., 2015) and compared with the available experimental data. Analysis shows that in a high temperature ambiance, use of temperature dependent thermo-physical properties for the gas phase and constant properties at average temperature for the liquid phase produce the best agreement with experimental data.
