摘要：In the present study the effect of swirl on NO x formation in non-premixed propane–air flame is examined. The experiments are conducted in an ax symmetric cylindrical combustion chamber for a range of equivalence ratio and swirl angle. The numerical simulations are carried out with the CFD code, Fluent. The turbulence k - ε model is employed. Both predictions and experiments show that as the swirl number increase, the temperature and the thermal NO x first slightly increase and then strongly decrease at the exit of the combustion chamber. The predicted results are in good agreement with the measured results.
