Abstract

This paper presents the results of a numerical investigation of sprayed hydrocarbon n-decane droplets evaporation processes. For the case of conductive heating heat fluxes on the surface of the evaporating droplet were examined. Characteristic curves unrelated to the initial droplet diameter were obtained after the aforementioned heat fluxes were normalized and displayed in Fourier time coordinates. The influence of initial droplet temperature and surrounding thermal radiation was investigated. As a result of this investigation, the possibility of the equilibrium evaporation state, evaporation rate and intensity changes during the process of evaporation were evaluated. In the result of energy interpretation of interaction between heat fluxes of different nature the characteristics of the process of evaporation were highlighted.
