Unsteady Flow of Viscous Liquid in Long Circular Tube

概要

論文の詳細を見る
Analysis is performed on the unsteady flow of liquid in a long circular tube in which the effects of tube ends are negligible. The analysis is made considering radial flow components and pressure distributions on the cross sections of the tube. Calculated transfer matrix which dominates velocity and pressure variation agrees well with experimental results under sinusoidal inputs. The proof is given that the pressure distributions on the cross sections are negligible. The viscosity of liquid affects the velocity distribution function. Numerical difference between exact transfer matrix and approximated transfer matrix which is calculated assuming Poiseulle flow, increases for higher frequencies especially in the neighbourhood of the characteristic frequencies of the pipeline.
