| Abstract: | Based on intensive investigation and successfully constructed wind tunnels in the past twenty years,the paper reviews some new ideas on the low(varying) turbulence wind tunnel design and they can be reference for engineering design.The paper gives the integrative curve for the design of stable section which plays a crucial role in reducing turbulence intensity,and the universal method for the contraction section which plays an important role in reducing turbulence intensity.Also it is proposed some personal... |
