Study of a sectional lumped parameter model using bond graphs for turbulent pipelines

摘要

Based on the improvement on the conventional sectional lumped parameter bond graph and introduction of the kinetic friction factor, a new sectional lumped parameter model using bond graphs for turbulent line is worked out. Experimental results shwoed that the goodness of identity between the simulation curves and the experimental curves is comparatively ideal, which implies that the new model has adequate accuracy. COmpared with the method of characteristic surves, the new model has less calculated parameter, simpler structure, and is suitable for modeling complex line systems.
