Time histories of droplet surface regression for: (a) binary mixture of n-heptane (𝑍₀₁=0.73) and n-hexadecane (𝑍₀₂=0.27) evaporating at an ambient temperature of 299.4 K, (b) different ternary mixtures containing equal volumes of three hydrocarbon fuels; n-octane, n-nonane, and n-decane (𝑇_∞=299.9 K); n-octane, n-decane, and n-dodecane (𝑇_∞=299.2 K); and n-octane, n-dodecane, n-hexadecane (𝑇_∞=296.5 K).
