Multi-phase modeling of non-isothermal reactive flow in fluidized bed reactors
Original language description
We investigate a model of a fluidized bed reactor decomposing liquid formic acid and producing gaseous mixture of carbon dioxide and hydrogen in the presence of microscopic solid catalytic particles. We describe the system, contained in a fixed control volume, as a mixture composed of four constituents-formic acid (FA), catalyst micro-particles (Cat), carbon dioxide (CO2) and hydrogen (H-2). For the individual mixture components, we distinguish partial densities and momenta, while we only consider one common temperature field for the mixture as a whole. We reduce the four-constituents model to a binary mixture model of liquid phase (Cat + FA) and gaseous phase (CO2 + H-2) which forms bubbles. Liquid phase is considered as a compressible viscous fluid with temperature-dependent density and viscosity depending on both the temperature (Arrhenius model) and the volume fraction of the catalyst particles. Physical interaction between the bubbles and the liquid is modeled under simplifying as
