A shoot-out contest to determine loss coefficients using CFD modeling for two prescribed duct fittings has been sponsored by ASHRAE Technical Committee: TC 5.2, Duct Design under the project number of ASHRAE RP-1493. The CFD technical expertise was provided by two CFD experts. The tasks of the CFD experts include soliciting contestants, developing the evaluation criteria, judge the submitted CFD methods for their practicality, i.e., if loss coefficient predictions can be achieved using commercial CFD software, whether they require an excessive number of nodes or extensive run times, and if they can be applied to developing flows with high turbulence intensity levels, recirculation, and complex geometries, etc. The CFD models were also assessed for their ability to predict loss coefficients within 15% of laboratory test values without previous knowledge of experimental data.
