LES Software for the Design of Low Emission Combustion Systems for Vision 21 Plants, Quarterly Report: April - June 2004

PDF Version Also Available for Download.

Description

Three SIMVAL LES calculations were completed this quarter: {phi} (equivalence ratio) of (1) 0.55, (2) 0.625, and (3) 0.7. The predictions were first analyzed, and then compared to existing experimental data of pressure dynamics, NO{sub x}, and CO emissions. It appears that the combustor flowfield changes for the {phi} of 0.55 case (compared to the other two cases), and this flowfield change results in a slight reduction in the pressure dynamics compared to the {phi} of 0.625 case. The predicted pressure rms values were 1.0 psi or less for the three cases. Good agreement was seen between predicted and measured ... continued below

The predicted pressure rms values were 1.0 psi or less for the three cases. Good agreement was seen between predicted and measured NO{sub x} emissions for the cases with {phi} = 0.55 and {phi} = 0.625. The CO predictions were higher than the measurements, but possible reasons were identified. A new SIMVAL dataset recorded June, 2004, is being processed and will be transmitted to CFDRC in the near future. The previous two datasets had known deficiencies. This new dataset will be compared to the LES predictions in the next quarter.
