Aspects of Mathematical Modelling of Heat and Mass Exchange at Burning of Droplet of Water Fuel Oil Emulsion

Abstract:

This paper presents some aspects regarding modelling of heat and mass exchange at burning of droplet of water-oil emulsion (WOE). Based on nonstationary differential equations of conservation of energy and matter in the liquid and gaseous phases, it was formulated a physical and mathematical model of heat and mass exchange in system of WOE drop-elementary gas cell. Unlike other models, in this model is taken into account the dependence of thermo physical properties of phase by temperature. The heating, micro explosion, vaporization and combustion stages of droplet burning were considered. For numerical solution and computer simulation of mathematical model has been developed an algorithm in Mathcad14 software. The numerical results were validated experimentally.
