摘要

摘要本文以带洞室的直道段水流为例，给出了两种二维水流简化模型的比较结果。测试了以下模型:二维势流模型、Stokes模型和Navier-Stokes模型。求解前两种方程采用边界元法，求解Navier-Stokes方程采用开放源代码库OpenFOAM。数值解的结果与水工实验室试验台上的测量结果进行了比较。测量采用ADV探头(声学多普勒测速仪)。最后，分析了数学模型计算结果与实验室测量结果的差异。

A Comparison of Simplified Two-dimensional Flow Models Exemplified by Water Flow in a Cavern

Abstract The paper shows the results of a comparison of simplified models describing a two-dimensional water flow in the example of a water flow through a straight channel sector with a cavern. The following models were tested: the two-dimensional potential flow model, the Stokes model and the Navier-Stokes model. In order to solve the first two, the boundary element method was employed, whereas to solve the Navier-Stokes equations, the open-source code library OpenFOAM was applied. The results of numerical solutions were compared with the results of measurements carried out on a test stand in a hydraulic laboratory. The measurements were taken with an ADV probe (Acoustic Doppler Velocimeter). Finally, differences between the results obtained from the mathematical models and the results of laboratory measurements were analysed.
