With the help of Integrated Performance Monitoring (IPM) and staff assistance from the Department of Energy's NERSC facility, United Technologies Research Center (UTRC) sped up a United Technologies-owned CFD code used to simulate multiphase flows. For the first time, this enabled the simulation of realistic fuel spray-related applications. Traditionally, such systems are designed by costly build-test-bust experiments due to inability to effectively model or to experimentally diagnose (measurements in the very near field of the spray are not possible due to obscuration effects). The ability to simulate this problem helps reduce design cycles substantially and provides new insights into the physics that can provide sprays with enhanced properties. UTRC has seen reductions in design cycles of at least 66 percent.
