STUDY ON DETERMINING RELATIVE ROUGHNESS OF ROUGHENED FLEXIBLE RUBBERS OF APRON
Pengfei Li · Neimenggu Nong-Mu Xueyuan xuebao · 2005
Professor Wen Heng and his students found that velocity of bottom of water is too much,and found that roughened apron by waste tires can adjust velocity and low velocity of bottom of water .This method can cope with the problem and the effect is significant. 21 kinds of roughness increasing and place condition of water on different cross section were designed.The aim was to fully understand the artificial roughness rubbers number,size/dimensions and assign form in different roughness relative,and the effect of it on the apron roughness and velocity of the bottom of water,and then found the potimum scheme of artificial roughness rubber's form and dimensions,which could be used in practice.
