Analysing the porous structure of packed beds of spheres using a semi-analytical approach
(Elsevier, 2019)In this paper methodologies are described for the analysis of the porous structure of cylindrical and annular packed beds consisting of spheres when the coordinates and sizes of the spheres are known. Methodologies to ... -
CFD analysis of thermal dispersion in a structured packed bed
(SACAM, 2018)Packed beds are generally modelled in a partial manner to avoid computational costs. This implies that only a small portion of the representative bed is modelled explicitly in CFD simulations, usually by assuming ... -
Conservation of scattered energy and asymmetry factor in the new Rotationally Symmetric Spherical Discretisation scheme
(Elsevier, 2016)A Rotationally Symmetric Spherical Discretisation (RSSD) technique has recently been developed for the discretisation of scattering phase functions in the Discrete Ordinates Method (DOM) in a consistent and rational manner. ... -
A laboratory scale fixed-bed coal conversion reactor. Part 1. Operation, reaction zone identification and industrial representativeness
(Elsevier, 2015)Fixed bed coal gasification and combustion operations form an important part in the global energy supply, and these processes are characterized by complex interactions which are difficult to study on an industrial scale. ... -
Porous structure of cylindrical packed beds with aspect ratios between 1 and 2
(Elsevier, 2020)The paper provides a comprehensive summary of the analysis of the porous structure of cylindrical packed beds with aspect ratios between 1 and 2. For the first time a proper geometrical explanation is given for the shape ... -
A systems CFD model of a packed bed high temperature gas-cooled nuclear reactor
(Elsevier, 2006)The theoretical basis and conceptual formulation of a comprehensive reactor model to simulate the thermal-fluid phenomena of the PBMR reactor core and core structures is given. Through a rigorous analysis the fundamental ...
