### MATHEMATICAL MODELLING OF RADIATIVE HEAT TRANSFER IN COMBUSTION CHAMBERS

**ABSTRACT**

Three main phenomena: fluid flow, chemical reactions and heat transfer comprise the processes in combustion chambers. The analysis and discussion of their mathematical modelling have been presented. The
requirements of the industry, which make it important to obtain an accurate prediction of combustion chambers performances, have been stated. The modelling of radiation and of radiative properties of
combustion products, the incorporation of turbulence as well as some recent modelling and a comparison with industrial tests have been reviewed. The up-to-date state of the art has been given. The latest needs of the
industry for the modelling of these processes have been stated. More conclusions have been drawn. Inter alia, one of them is that the inflow of combustion gases at the adiabatic flame temperature at
burners locations is a good approximation for the furnaces in large industrial and auxiliary boilers. The recommendations for further research in this field has been given. These can be generally grouped in
three areas: (1) theoretical research, (2) experimental work, and (3) industrial application.
