The fixed bed nuclear reactor concept [PDF]
Energy Conversion and Management, 2008 In the present work, the basic features of a new reactor type, the so called Fixed Bed Nuclear Reactor (FBNR) is presented. FBNR is a small reactor (40 MWe) without the need of on-site refueling. It utilizes the PWR technology but uses the HTGR type fuel elements.

Dynamics of a three-phase upflow fixed bed catalytic reactor [PDF]
, 1999 A dynamic model of an upflow fixed-bed catalytic reactor is developed to examine numerically transient axial temperature and concentration profiles obtained for the consecutive hydrogenation of 1,5,9-cyclododecateriene on a Pd/Al2O3 catalyst.

A novel reactor for determination of kinetics for solid catalyzed gas reactions [PDF]
, 1994 A novel perfectly mixed laboratory reactor for determining kinetics of heterogeneously catalyzed gas-phase reactions has been developed. Perfect mixing is achieved by circulating the gas in the reactor using an axial flow impeller in a well streamlined ...

Mathematical Modelling of Volatile Gas Using Lattice Boltzmann Method
Environmental and Climate Technologies, 2020 This study investigates the behaviour of pyrolysis gas, generated by the thermal decomposing of biomass, in a pilot size reactor. The discreet mathematical model, Lattice Boltzmann, has adopted for mathematical simulation of flow of pyrolysis gas across ...
