PHYSICAL AND NUMERICAL MODELLING OF INTERNAL AERODYNAMICS OF THE VORTEX FURNACE WITH DISTRIBUTED TANGENTIAL INPUT OF BURNER STREAMS

Read more The work is devoted to experimental and numerical modelling of internal aerodynamics of a new type furnace for the thermal power plant steam generator with technology of pulverized-coal combustion in vortex flow. Measurements of aerodynamic features of the flow in the laboratory air isothermal model of the furnace have been performed with twocomponent laser Doppler velocimeter. Numerical simulation of three-dimensional turbulent isothermal flow in the laboratory model has been carried out with the use of CFD package FLUENT. Detailed 3-D flow structure in the studied model has been obtained. The agreement between numerical predictions and measurements on mean flow velocity distributions has been shown.
