Grahic Jump Location
Effect of temperature and air split on the percent standard deviation in the laser transmission for the outlet stream of the SPP with No. 2 low sulfur diesel fuel-air mixture at ϕ=0.68. Legend: First stage airflow rate divided by the second stage airflow rate, and nominal first stage temperature in Kelvin. Long second stage used.
Grahic Jump Location
Standard deviation in transmission versus mean transmission. Long second stage for the SPP.
Grahic Jump Location
Effect of SPP temperatures and air split on NOx for natural gas-firing of the JSR. Legend: First stage airflow rate divided by the second stage airflow rate and nominal first stage temperature in Kelvin. Long second stage used.
Grahic Jump Location
Effect of fuel type on NOx JSR combustion temperature of 1790 K and residence time of 2.3±0.1 ms. The SPP conditions are outlet temperature of 623 K, and first to second stage airflow ratio of 1.
Grahic Jump Location
Same conditions as Fig. 8, except the fuel NOx formed through 100% conversion of FBN is deducted for the diesel fuels
Grahic Jump Location
Effect of fuel type on CO for JSR combustion temperature of 1790 K and residence time of 2.3±0.1 ms. The SPP conditions are outlet temperature of 623 K, and first to second stage airflow ratio of 1.
