| Abstract: | This paper researchs into the acceleration pressure loss of the two phase flow of the thin phase positive pressure pneumatic conveying system of flour and bran whose concentration is u<10kg/kg and whose transporting distance is between 30 and 90 meters. From the function principle the calculation formulas of the start acceleration pressure loss and reaccelerating pressuer loss are derived. And through the experiment the speed ratio of air before and after and after acceleration is found. |
