low speed flow

It is different with the traditional DVM. And comparing this model with theory analysis and numerical solution, in the low speed flow, it shows excellent agreement when Knudsen number from slip region to transfer region.

将这种模型与数值模拟和理论分析结果的对比表明，离散模型不仅能够模拟低速流动问题，而且还能够模拟Knudsen数从滑移领域到过渡领域内的气体流动，并且计算速度快。

For low speed flow problems, because of the highly nonlinear coupling of the low bulk flow velocity and the high velocity of molecules' thermal motion, and usually over-estimate the true flow velocity in such cases and lose its authenticity.

对于低速流动问题，由于较低的流动速度和较高的分子热运动速度的非线性耦合，流体的流速被大大地高估，失去其真实性。
