All scale simulation of the two systems provide the basis for design and improvement of air conditioning system fans to improve the internal flow, increase air volume, and reduce the noise. The conclusion that disturbance on flow of nuzzle outlet is the main sources of measurement error about 5% can be proved by the comparative analysis of the results between computation and experiment. Through Optimization Design of Partial Structure they all meet the industry standard, measurement error less than 1.5%.展开更多
