Study Of Chaotic Properties Of Pipe Gas-solid Flow Based On Pressure Difference

For the problem that on-line monitoring of primary air of direct firing pulverizing system can't be complete achieved, the chaotic properties of parameter change of two-phase flow in pipe is analyzed in the paper, according to the pressure difference signal of two-phase flow system. The pressure difference signal was acquired under different air and pulverized coal flow condition on gas-solid test-bed. On the basis of studying chaos theory and its application, a set of software used to analyze characteristic numbers of chaotic time series is accomplished, deterministic chaos theory is applied to the pressure difference series by the software, and some preliminary conclusions are drawn.Li Yu (Thermal Power Engineering)Directed by Prof. Chen Hongwei, Prof. Guan Jinfeng...
