Abstract [eng] |
A free from droplet size limitations, combined analytical-numerical solution methodology for unsteady heat and mass transfer in dispersed evaporating liquid is presented. Temperature and pressure jumps in the Knudsen layer were taken into account in a numerical investigation scheme where evaporating droplet surface temperature was calculated by the fastest descent method minimizing the energy flow balance. Heating and evaporation of water droplets in air flow were numerically investigated. The importance of a parameter expressed by the droplet surface temperature ratio to the temperature of equilibrium evaporation during conductive heating, for evaluation of a dispersed liquid thermal state change was highlighted. |
