Title:
Numerical Simulation and Experimental Investigation of the Fixed Bed Gasification of Char with Focus on Pore Diffusion
Abstract:
Accurate modeling of the reaction rate of char particles is decisive for precise computational fluid dynamics simulations of gasifiers. Pore diffusion limits the reaction rate at medium temperatures and strongly depends on the pore size. In most of the present research, pore diffusion is either completely neglected or modeled with a single mean pore size. This work introduces a particle model with two pore sizes. Large pores transport the reactant gases into the particle and distribute them to s...     »
