Analysis on Interference Force to Large Coal Particle Transport in the Pipelines

摘要：

　　Slurry is belonging to the state of suspension of heterogeneous flow when transporting large coal particle in inclined pipeline.The large coal particles in inclined pipeline are not only recruited to the drag giving by carrying fluid but also the interference force from other particle.In order to study on interference force to large coal particle in the pipeline,to be use of already theory and experimental data to study,and discover The traditional force balance equation can not satisfy the stress of the large coal particle.So conjecture it may be has many unknown resistance in inclined pipeline.Base on the research,we can get the raise interference force coefficient Kc by using data fitting to revise traditional force balance equation.
