Analysis and Optimization of Flow Field Characteristics of Thin Volute Bottom Structure
The structural design of thin volute is a key step to push the development of ultra-thin exhaust hood prod-ucts towards lightweight,thin and beautiful. As the thickness of the volute compresses,the height of the blade decreases,which means that the wind-facing area of the blade decreases,and the overall performance of the blade also decreases. Therefore,the unreasonable structure of the motor bracket inside the thin volute makes the flow field more likely to be turbulent,increase turbulence,resulting in performance loss. In this paper,the simulation of different working conditions for the volute bottom structure design to provide a basis.
