Computational Fluid Dynamics Prediction of Subsonic Axisymmetric and Two-Dimensional Heated Free Turbulent Air Jets

A study was conducted to evaluate the accuracy of a commercial computational fluid dynamics (CFD) code (CFDRC-ACE+) for predicting incompressible air jet flows with simple geometries. Specifically, the axis- symmetric and two-dimensional heated air-jets were simulated using a standard k- epsilon turbulence model. These CFD predictions were directly compared to an extensive compilation of experimental data from archive literature. The round jet results indicated that the code over-predicted the velocity-spreading rate by 24% and the temperature spreading rate by 29%.Naval Postgraduate School Monterey CA is the author of 'Computational Fluid Dynamics Prediction of Subsonic Axisymmetric and Two-Dimensional Heated Free Turbulent Air Jets' with ISBN 9781423533290 and ISBN 1423533291.
