Název v původním jazyce

Verifying the Prediction Result Reliability Using k-ε, Eddy Dissipation, and Discrete Transfer Models Applied on Methane Combustion Using a Prototype Low-Pressure Burner

Popis výsledku v původním jazyce

The article aims to verify the accuracy of a method to simulate the combustion chamber with a low-pressure prototype burner equipped with a specific “mixing element” and air baffle. The burner has an output of 4 kW and combusts methane. In detail, the article evaluates the accuracy of the final courses of temperatures and CO concentrations in the combustion chamber, which were obtained having combined the mathematical models k-ε, Eddy Dissipation and Discrete Transfer. CFD software CFX was used for the solution and visualisation of the results. The verification measurements imply that the final course of temperature plotted on the vertical axis of the combustion chamber differs from the real course by +21.7% on average. The predicted CO concentrations are relatively satisfactory in the chamber locations with lower temperatures – at the combustion chamber outlet the deviation from the measured value was +31.8%. Overall, the applied method may be considered acceptable to simulate the thermal field in a combustion chamber with the described burner.
