| Abstract: | Recently the pneumatic conveying is of a new technique,This paper gives basic research of the two-phase flow of gas-solid for the straight horizontal pipeline,presents three formulae,i.e.the formula of the sus pension veiocity of particles,the formula of the velocity of motion of pacticles and the formula of pressure loss.Results of calculation by these formulae in a practical example have been proved to be satisfactory and used to design or improvement for pneumatic conveying devices. |
