【Hyperbolic Method to Explore Multiplicity Flow Solutions in a Four-Sided Lid-Driven Cavity】
#论文# #空腔# #驱动# #计算流体力学#

The two-dimensional flow driven by boundaries moving inside a cavity is considered to be a classical problem of computational fluid mechanics. This study uses the hyperbolic method in order to study steady-state flow solutions of the four-sided lid-driven square cavity in two dimensions. And a classical Riemann solver is used to solve the incompressible Navier-Stokes equation with the artificial compressibility method. A simple second-order finite-volume discretization on a rectangular grid using upwind advective and dissipative fluxes is employed.

They found that middle-aged people with higher measures of abdominal fat scored worse on measures of fluid intelligence as the years went by.

【重点词汇】abdominal 腹部的

【结构分析】主干：They found that...，that引导的句子为宾语从句，其中middle-aged people为主语，scored为谓语动词，worse为副词修饰动词scored;with higher measures of abdominal fat为介词短语，修饰people，on measures of fluid intelligence介词短语作状语

as the years went by为as引导的时间状语从句，随着时间的流逝

【参考译文】他们发现，随着时间的推移，腹部脂肪含量较高的中年人在液态智力测试中的得分越来越低。
