Краткое описание

Three-dimensional CFD modelling of mixing of steam plasma jet with atmosphere in thermal plasma reactor has been carried out. Centerline temperature of steam plasma jet at the reactor input was approximately 23,000 K and mean inflow plasma velocity was approximately 2,600 m/s. Interaction of plasma jet with nitrogen flowing into the reactor was studied. The modelling simulates conditions in experimental reactor for biomass gasification. Standard, RNG and realizable k−ε models, and standard k−ω model were used for the simulations. Steam plasma and nitrogen transport and thermodynamic coefficients used in the computations were determined under the assumption of existence of LTE. Results for temperature, velocity and density distributions are discussed and presented as images obtained from the FLUENT code, for currently used reactor geometry setup and plasma jet characteristics.
