Numerical modeling of a vaporizing slurry droplet
Abstract
A numerical investigation of the fundamental processes governing the energy, mass and momentum exchanges between the solid, liquid and gas phases of a vaporizing slurry droplet is presented. The configuration studied consists of an isolated slurry droplet containing a single solid particle in its core, and which is vaporizing in a convecting environment. The model allows for independent motion of the solid particle core along the axis of symmetry of the slurry droplet, and it accounts for variable gas-phase properties as well as variable liquid-phase viscosities and latent heat. Additional features of the model include consideration of the surafce blowing effect and droplet surface regression due to vaporization, internal liquid circulation with transient droplet heating, and droplet deceleration with respect to the free flow. The numerical calculation employs an iterative solution procedure that has been successfully used previously for an isolated all-liquid droplet.
