过去,建立管内不恒定流的数学模型,基本上都是从描述其物理现象的偏微分方程入手建立机理模型.本文试图采用系统辨识的原理,通过实验手段建立管内不恒定流的统计模型.
In the past, the establishment of a mathematical model of unsteady flow in the pipe basically started from the description of the physical phenomena of partial differential equations to establish a mechanism model.This paper attempts to use the principle of system identification, experimental methods to establish a non-constant flow within the pipe statistical model.
