Time-dependent Poiseuille flow of a viscous compressible fluid confined between two planar walls is studied for a partial slip boundary condition with frequency-dependent slip length. After an initial uniform impulse parallel to the walls, the flow pattern quickly becomes nearly parabolic. For a narrow gap, a dynamic slip length can lead to damped oscillations of total fluid momentum.
研究了在具有频率相关滑移长度的部分滑移边界条件下,限制在两个平面壁之间的粘性可压缩流体的时间相关泊肃叶流动。在平行于壁面施加初始均匀冲量后,流动模式很快变得接近抛物线形。对于狭窄间隙,动态滑移长度会导致总流体动量的阻尼振荡。
