Tandem cylinder benchmark
The First Workshop on Benchmark problems for Airframe Noise
Computations (BANC-I) was held in Stockholm, Sweden, June 10-11,
2010. The workshop was organized by the Discussion Group on
Benchmark Experiments and Computations for Airframe Noise
(BECAN),1 which is jointly sponsored by the Fluid Dynamics and
Aeroacoustics Technical Committees of AIAA.
The BANC Tandem Cylinders model is available here:
