Comparison of Numeric Methods that Simulate Energy Transfer by Radiation

Popis výsledku v původním jazyce

The publication deals with the comparison of mathematic models that simulate heat transfer by radiation and of models of spectral characteristics of the burnt gases. The heat transfer in the combustion chamber with the shape of rectangular cross-sectionof 200 x 288 mm and 1,000 mm high has been numerically analysed by means of the individual models. A low pressure burner of the ejection type and of the power output from 20 to 40 kWs is located in the lower part of the combustion chamber. As the heatinggas, methane is used. The interest is especially focused on the evaluation of the radiation intensity in the combustion chamber and on the heat fluxes to the walls that are predicted by the models. Results of the P1 and Discrete Transfer models and results of the Gray and MultiGray models of spectral characteristics of the burnt gases have been compared. A part of the research is also the recommendation dealing with the individual models usability.
