General purpose Mathematical Model for an Axial flow Fan

A traditional mathematical model for axial flow fans with adjustable rotating or static vanes usually suffers from a range of problems, such as a low static precision of the model and a relatively great difference between its dynamic regulation process characteristics and those of an actual fan, etc. To cope with this problem, a general purpose mathematical model for the above mentioned axial fans has been set up based on the specific features of their static performance curves and the relevant theories and principles of axial flow fans. The calculation examples and usage practice indicate a high static precision and fine dynamic regulation features of the above mentioned model. It can be employed for the real time simulation of axial flow fans, the on line monitoring of fan performance and the forecast of malfunctions and failures, etc, revealing its comprehensive usage adaptability.
