Modelling of multi-component droplet evaporation under cryogenic conditions by Xu Xiaochun, Privat Romain, Jaubert Jean-Noël, Qu Yongfeng, Bonnissel Marc

“…The falling speed of the sprayed droplets was calculated with the momentum equations considering three forces (gravity, buoyancy and drag) applied to a droplet. To evaluate the mass and heat transfer between the sprayed droplet and the surrounding gas phase, a gaseous boundary film of sufficient thinness was assumed to envelope the droplet, while the Peng-Robinson equation of state was used for estimating the phase equilibrium properties on the droplet’s surface. …”
