Entrained flow gasification is a promising technology for conversion of biomass into valuable fuels and chemicals. Residues and byproduct formed during a gasification process possess a significant challenge prior to the production of synthetic fuel (biofuel). Present work focuses on the simulation of an entrained flow gasification reactor in Barracuda, which is based on the Computational Particle Fluid Dynamics (CPFD) modelling. The model is validated against experimental gas compositions reported in the literature. The model was used to study the flow behavior as well as the distribution of product gases and temperature inside the reactor. Simulations showed zones of high and low-temperature regions suggesting different reactions zones such as a partial combustion zone near a fuel injector followed by a gasification zone. The flow behavior inside the reactor shows zones of recirculation, spreading and the fast flowing zone. Results from the product gas distributions inside a reactor supports the reason behind the zones with different temperature.
