In this work we compare two different modelling strategies for the simulation of wood gasification in a dense fluidized bed. In the first method we adopt an Euler-Lagrange approach where the fluid phase is modelled as a continuum and the particulate phase is modelled on the individual particle level using the Discrete Element Method (DEM). In the second method we use an Euler-Euler or continuum approach where the multiple solid phases for wood and char particles are treated as a continuum. Both models allow the time-dependent prediction of velocity, temperature, and composition fields. Both models have been run to a statistically stationary state. We compare the numerical results of both methods against each other and with experimental data obtained at a laboratory scale bubbling fluidized bed reactor.
