Diffusivity, mass diffusivity or diffusion coefficient is usually written as the proportionality constant between the molar flux due to molecular diffusion and the negative value of the gradient in the concentration of the species. More accurately, the diffusion coefficient times the local concentration is the proportionality constant between the negative value of the mole fraction gradient and the molar flux. This distinction is especially significant in gaseous systems with str… WebMar 18, 2015 · The liquid fuel was pure ethanol (CH 3CH 2OH, molecular weight of 46.07, purity.99.5%), which was ignited at the outlet of the nozzle, forming the small diffusion flame in the quiescent air at room tempera-ture and atmospheric pressure.
