The aim of the current thesis is to model the various fluid-particle interactions in an 150g/h bubbling fluidised bed reactor. Mass, momentum and heat transfer from the bubbling bed of the reactor to the discrete biomass particles are modelled and analysed. The Eulerian-Eulerian approach is used to model the bubbling behaviour of the sand, which is treated as a continuum. The biomass particle motion inside the reactor is computed by integrating the equations of motion using drag laws, dependent on the local volume fraction of each phase. Reaction kinetics are also incorporated in the computational code according to the literature, using a two stage global model which takes into account the intra-particle secondary reactions due to the catalytic effect of char, resulting on secondary vapour cracking.
