Numerical investigation of droplet evaporation phenomena in the spray methods

Physical phenomena of the droplet evaporation occurred in the spray pyrolysis reactor tube has been studied. This model simulation was expected to predict the process occurred in the reactor tube and predicted the size and morphology of particle. The dynamical model of particles influenced by macroscopic parameters such as reactor wall temperature, flow rate carrier gas and concentration of precursor have been successfully simulated. The size of the particle, the number of aqueous vapors around droplet, air temperature around the droplet, temperature of droplet and solution concentration profile of particle in the reactor tube were simulated. The desired final particle can be achieved by controlling these factors.
