A distributed parameter model for the drying of multicomponent aerosol and sessile droplets
Jakub M. Gac , Leon Gradoń
AbstractThe new distributed parameter model is formulated for the purpose of the investigation of a drying of suspended and sessile droplets of multi-component solutions. The main feature of this model is the division of a droplet/wet particle into the shells and formulating the mass and heat balances for each shell, which have a shape of spheres in a case of aerosol particles and a shape close to the cylinders in a case of sessile droplets. Presented model takes into account the crust formation during the second stage of drying. This effect is neglected in existing models of the phenomenon. The model predicts the dimension and a shape of particle or formed deposits. It also indicates the possibility of a segregation of components when their solubility and diffusion coefficients are different.
