Abstract:
The exact knowledge of reaction rate, diameter, and density of a char particle is important for precise computational fluid dynamics (CFD) simulations of gasifiers. Most of the present research treats char particles as homogeneous with respect to density and composition. Diameter and density evolve according to power law relations, which are empirical and hard to validate. In this work, char particles are subdivided into multiple homogeneous shell–like volume elements. It allows the calculatio...     »
