Abstract:
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 showed 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. The new
model has less calculated parameters, simpler structure, and is suitable
for modeling complex line systems.
