The fluid diffusion in the pressure driven micro-channel is simulated numerically.
对压力驱动微通道流中的扩散进行了数值模拟,说明微尺度效应使流体扩散的不均匀性趋于明显;分析了在各种W/D情况下,距离管道壁面各个层面上的扩散尺度变化,说明了微管道中的对流和壁面效应对于扩散尺度的影响。
This paper mainly discusses that thermos-diffusion theory than pressure-driven theory is a more important factor and applies the thermos-diffusion theory to explain the reason why the concentration of Radon changes with temperature,which may suggest a more reasonable measure in practice and economy for reducing Radon-enter indoor by illuminating theoretic rationality according to metrical data.
