摘要：
The possibility of using a two-port model to analyze the source character of an in-duct axial fan is investigated. It is found that in the plane wave region the tested fan closely resembles an ideal dipole located at the fan blades. This finding is in agreement with earlier investigations which have been performed. These investigations were based on incomplete source models or direct observations of the variation in acoustic output with different parameters: e.g., fan speed and duct length. One important application of the result is a simplified procedure for determining the two-port source data of axial fans. (C) 1995 Academic Press Limited
