波纹通道内充分发展层流流动的简化分析

Simplified Analysis of the Laminar Flow Fully Developed Inside the Corrugated Passages

对平行放置的波幅与波数不同的两块波纹板形成的通道内的定型层流流动,以壁面波纹的波幅为小量进行摄动,建立近似分析模型,得到了速度分布表达式,考察了流量和阻力系数与壁面波纹的波幅和波数之间的关系。结果表明,流量随波纹板的波幅和波数的增大而增大,而壁面阻力则随两块板相对波数的大小、波幅和波数呈现不同的变化。

Perturbed was the fixed type laminar flow in the passages formed by two corrugated plates having different amplitudes and number of waves placed in parallel with the amplitude of the wall surface waves serving as the small value and established was an approximate analytic model.On this basis,a velocity distribution expression was obtained and the relationship between the flow rate and the drag force coefficient as well as between the amplitude and number of the wall surface waves was investigated.It has bee...
