ABSTRACT
The aerodynamic performance experiment of 3 kinds of axial-flow pneumatic extinguishers about different blade angle have been carried out firstly. Based on the N-S equation and the K-ε model, the internal flow field numerical simulation of axial-flow fire-fighting under the design condition has been completed. The internal flow field contours of center section have been obtained, the internal flow situation of axial-flow pneumatic extinguisher under the design condition has been analysed. The performance curve by the numerical simulation and the results by the aerodynamic performance experiment were in a good agreement, which indicated the validity and correctness of the numerical simulation. Finally the aerodynamic performance of 6 blade numbers, 38° blade angle axial-flow fire-fighting fan is best and it can be used in the design of the axial-flow pneumatic extinguisher.
