Movement analysis on materials flowing through a vertical pipe based on MATLAB

Through analysis on the interaction and relationship between materials and airflow in the vertical pipe of an impeller blower, movement equations of materials flowing through the vertical pipe was established and the movement of materials was numerically simulated with the adoption of computer analysis software MATLAB. The reliability of the equations and numerical simulation was verified through comparison with the experimental values in related references. Basis was provided for further optimization of geometric parameters of the vertical pipe, reasonable selection of rotational speed of throwing/blowing impeller, reduction of power consumption of an impeller blower and the improvement of throwing/blowing efficiency.
