抄録

From the distribution of solids in the horizontal pipe the authors have deduced a result that the rate of fall of granular solids in the turbulent flow is smaller than the flow fluctuation, which approves the suspension of solids in the flow. Owing to the mutual collision of solids and the collision of solids against the pipe wall, solids are not conveyed in a constant state, but in a perpetually varying state. When solids are conveyed in a horizontal pipe, the velocitv distribution of air is not symmetrical with respect to the pipe axis. The authors have expressed the asymmetrical velocity distribution of air in consideration of both the weight ratio of solids to air in flow and the friction velocity.
