The spherically symmetric droplet burning characteristics of Jet-A and biofuels derived from camelina and tallow

► Camelina and tallow HRJ fuels are compared with Jet-A using spherical droplet flame. ► Jet-A is more sooty than the biofuels due to its higher aromatic content. ► Droplet burning rates of camelina and tallow HRJ fuel are very similar to Jet-A. ► The two HRJ fuels also match Jet-A in terms of flame and sooting dynamics. ► The spherically symmetric droplet flame is useful to benchmark new generation fuels.
