本文用动量方程和相应的密度方程作为控制方程,建立数值解来研究二维水库的下潜流问题。在一个容积有限的水库中,下潜流只能是非恒定流动,因此采用非恒定的 N-S 方程。本文用控制容量法建立数值方程,并用帕特恩克和斯波尔丁的SIMPLE 程序求解压力场-速度场之间的相互作用。本文采用极坐标系模拟典型的斜坡水库。对层流和紊流两种状态都作了研究。紊流研究采用 K-ε模型,其中在K方程中包括有排斥浮力的能量项。数值运算在明尼苏达大学的 Cary 1型计算机上实施。
In this paper, the momentum equation and the corresponding density equation are used as the governing equations to establish the numerical solution to study the submarine flow problem in 2D reservoirs. In a reservoir of limited capacity, the dive current can only be a non-constant flow, so a non-constant N-S equation is used. In this paper, we establish the numerical equation by the control volume method and use the SIMPLE program of Parthenk and Spalding to solve the interaction between pressure field and velocity field. This paper uses a polar coordinate system to simulate a typical slope reservoir. Both laminar and turbulent flow conditions have been studied. The turbulence study used a K-ε model in which the energy terms that exclude buoyancy are included in the K equation. Numerical calculations are performed on the University of Minnesota Cary 1 computer.
