Mathematical models of combustion, convection and heat transfer in experimental thermic device and verification

Abstract

The presented paper deals with the analysis of turbulent burning and with transport of energy and momentum. The article specificity lies in the fact that these processes are analysed in the horizontal furnace in which the screw reactor is placed. This reactor processes organic raw materials continually and thermally. Volume input of the raw materials is about 60 kg per hour. Solution of this issue comes from the measured energy responses of this device and from the principles of mathematic 3-D modelling. The main aim is to introduce a methodology of the combined modelling of the turbulence, burning and radiation for the monitored case and to verify it on the basis of experimentally obtained data.
