An experimental investigation of the sealing characteristics of a zero pressure , zero leakage lubricated spiral groove mechanical seal 液體潤滑螺旋槽機(jī)械密封性能的實(shí)驗(yàn)研究
A computed study was undertaken to determine the effects of minute vortex generator jets on the zero pressure gradient turbulence boundary layer 本文采用數(shù)值模擬方法研究了微型空氣渦流發(fā)生器對零壓力梯度湍流邊界層的影響。
The demarcation point of , which is the parameter in erf ' s yield stress equation , is 2 . 0 . for , the dynamic characteristics of the clutch are remarkably different from those for . thirdly , the linear stability of plane shearing flow with non zero pressure gradient is studied 論文第三部分對電流變液非零壓力梯度平板剪切流動的穩(wěn)定性進(jìn)行了分析,提出流場對屈服應(yīng)力達(dá)到飽和的概念;并得出平板壁面剪切運(yùn)動以及電流變液屈服應(yīng)力的提高,都將使流動穩(wěn)定性增強(qiáng)的結(jié)論。
