yesterday, Dr Liping Xu was invited to my company to give a talk which is based upon John's paper. He mentioned that the compressor of PW6000 of PW was designed using the company's in-house CFD programs and NASA's CFD programs and tests show that the compressor was a few percents lower in efficiency than predicted. He said it was a typical example of mis-using CFD and leading to a catastrophe. |
