unsteady Navier Stokes equations的意思|示意

Transonic tube wind tunnel flows over supercritical airfoils with slots on both upper and lower walls have been simulated by using compressible unsteady two dimensional Navier-Stokes equations.

本文采用二维可压缩非定常N-S方程模拟了带有上下开槽壁的跨声速二维管风洞中超临界翼型绕流的流场。

The thesis established the flow model based on one-dimensional, unsteady, compressible, Navier-Stokes equations, and discrete the governing equations using a finite-volume formulation.

本文基于一维非稳态多分支非定常流，建立了相应的数学模型，采用有限容积法理论对方程进行数值离散分析。
