The Study Of Numerical Simulation About Ventilation Vane Of The Wind Driven Ventilator

Nowadays Wind-Driven Machines(also called wind turbo blower or no power exhaust blower) as a kind of power machine has widely used in many fields, which is driven by nature wind power without consuming electricity,it has been used for some producing and living such as the ventilation of factories and some high buildings. To solve this problem, the machine should be fixed on the building's roofThis paper simulated the field of the whole Wind-Driven Machine, and also simulated the vane of the Wind-Driven Machine, and discussed the influence of the flow rate and efficiency with the change of different figure of the vanes which can supply the firm basis of theory and experiment for the industry product in future.This paper simulated the field of the whole Wind-Driven Machine, and also simulated the vane of the Wind-Driven Machine. Drew geometric model by CAD software PRE, and importing them into GAMBIT to build up grid pictures, then using CFD software FLUENT which is widely used to calculate the flow field. The equation is K-E model, the coupling of velocity and pressure used SIMPLE method. Momentum turbulence kinetic energy and turbulence dissipation rate are second order upwind. And changed different figures of the vane to discuss the influence of the flow rate and efficiency with the changes of different figure of the vanes...
