The Structure and the Flow-field Mathematical Model of the Air-curtain Dust-controlling Fan

In this paper, by applying air-curtain dust-controlling technique, a new fan, the air-curtain dust-controlling fan, is introduced, and has been manufactured. And its structure and application are described. Simultaneously, the theory of short-circuit flow field is put forward. Based on the principle of flow field superimposition, a mathematical model is established for the flow field. A new and highly efficient product is provided for the harnessing engineering of dust environment.
