TL;DR: In this paper, the partial differential equation governing the droplet growth was analyzed for the slag vapor and droplet ridden combustion gas stream in an MHD channel and numerical solutions were obtained for environments representing the flows through the channel and diffuser.
Abstract: Nucleation and droplet growth were analyzed for the slag vapor and droplet ridden combustion gas stream in an MHD channel. Numerical solutions were obtained for environments representing the flows through the channel and diffuser. It was found that the partial differential equation governing the droplets is very unstable because of the precipitous manner in which the nucleation rate varies and the strong dependence of the droplet growth rate on the droplet size. This difficulty was circumvented by a logarithmic transformation of the independent variable, r. The numerical solutions showed that evolution of the droplet size distribution proceeds through a succession of rather delicate balances between the size-dependent condensation and evaporation rates and the nucleation rate. These balances are largely dictated by the supersaturation ratio. Growth at an early stage of the submicron size droplets and the subsequent nucleation of the extremely small droplets engender a bimodal size distribution at the end of the channel or at the beginning of the diffuser depending on the supersaturation ratio. This bimodal nature is preserved through the diffuser. Higher slag mass content of the gas stream was found to result in a more pronounced bimodal distribution at the end of the diffuser. Also, themore » higher slag content was found to accelerate the growth such that the entire spectrum is squeezed toward the larger-radius region of the size spectrum. Consequently, the average size of the droplets is larger at the end of the diffuser when the slag content is raised.« less
