| Abstract: | This paper presents the measurement of gas-solids flow rate in the pipe with extended-throat venturimeter. Three kinds of particles: talcum powder, glass beads and pulverized coal are involed. 54 curves are obtained at different gas flow rate for all kinds of particles. It shows that the pressure drop ratio is linear with loading ratio and all the curves for same particles can be fitted into one with satisfactory linearity. The influences of particle diameter on the choice of position of taps and the length of throat of venturi are also studied in this paper. The numerical calculation with a quasi-one-dimentional model gives a good results compared with the experimental data. |
