概要

論文の詳細を見る
In this paper, the pressure response to the linear change of a flow rate in oil pipelines is treated. The theoretical expressions representing the shape of the pressure response to it have been derived, and the influences of the parameters in the pipeline-systems on the pressure response have been elucidated.The theoretical expressions for the pressure response including nondimensilnal parameters have been indicated as a sum of series, and experiments have been performed by changing the inner diameter of pipeline, coefficient of kinematic viscosity of oil and linearly changing time of the flow rate, respectively. The theoretical expressions and the experimental results agreed with each other, and the results were examined closely. The expressions representing the maximum pressure and the damping properties of the shape of the pressure response have been derived approximately.
