N2 - The possibility of using a constant property analysis for multicomponent diffusion systems where interaction between fluxes is not ignored, is investigated in this work. The results are compared with an exact multicomponent variable property analysis and a constant property analysis utilizing the "effective binary diffusivity" approximation. In order to demonstrate and test this approach an isothermal evaporation problem of a multicomponent mixture into a free stream of inert gas is analysed. Also the case of flat plate transpiration mass transfer is considered. Results show that also when the properties of the chemical species involved in the diffusion process are markedly different, the use of a constant property analysis with multicomponent diffusivity, evaluated at a reference state, is quite accurate.
