Abstract

The validity of flowfield predictions resulting from the choice of inlet velocity profiles is assessed. Results demonstrate that realistic predictions are forthcoming only from the inclusion of realistic axial, radial, and swirl velocity profile as inlet conditions. The ensuing flowfields are characterized by means of velocity profile and streamline patterns, and illustrate the large-scale effects of inlet swirl and velocity profiles on flowfields. Clearly, measured inlet profiles must be used in future turbulence modeling development studies for improved simulation of flowfields.
