Internal Flow and Fan Characteristics of a Cross-Flow Fan

摘要

Since the configuration and variable flow rate characteristics of a cross-flow fan can be improved by changing the rotor length, they are increasingly used in the rear cooling units of mini vans, in wcich compact design and low noise characteristics are required. Although many studies have been carried out the flow and performance and it has been shown that the internal flow, depending on the configuration of the casing, has a large effect on the performance, the methods for predicting the performance and designing an efficient fan have not yet been established.
