unsteady-flow effect
解釋
非定常流效應-
For a soil or rock of water - lacked, a heat transfer theoretical model is developed, which is a steady or unsteady, the results show that reservoir temperature, thermal diffusion coefficient, inlet temperature, flow rate of and run time of ground source heat pumps have an effect directly on heat transfer process of dhe. it can deduce that intermit running is favorable for this type of soils and rocks
對于貧含水地下巖土層建立了穩態與非穩態傳熱的理論模型，分析結果表明，巖土層的熱儲溫度、導溫系數、埋地換熱器進水溫度、流量以及地源熱泵系統的運行時間或開停機比，都對埋地換熱器的傳熱過程產生直接影響，可以推斷，對于該類型巖土層的地源熱泵系統，採用間歇運行將是有利的。 -
This method makes it possible for investigating the unsteady nonlinear potential flow in a complicated environment with higher efficiency. the aerodynamic forces of a wing in couple motion of heave and pitch with ground effect are analyzed in detail based on the numerical result. it is shown that a thrust force exists when the wing is in heave motion
深入系統地分析了存在表面效應時機翼運動規律和氣動力之間的關系，研究結果表明，機翼升沉運動產生的推力與升沉速度幅值的平方成比例，推力和推進效率和振蕩頻率成反比；機翼的俯仰運動可以調節推力和推進效率，但是單純的俯仰運動不會產生推力。 -
First, the difference between the stm and utm is compared and analyzed. the results show that it can accurately simulate the unsteady flow process of piston wind and the pollutant distribution in tunnel after train left the tunnel, can analyze and calculate the good effect of inertial action of piston wind if using utm
文中首先分析和比較了傳統隧道通風設計所採用的恆定流理論與非恆定流理論的差別，表明運用非恆定流理論不僅更能準確模擬隧道內活塞風的非恆定流動過程，而且能模擬列車通過隧道過程中隧道內污染物濃度的分佈，同時還能考慮利用隧道內氣流（活塞風）慣性作用促進隧道通風，節約通風能耗。 -
By using a reynolds - averaged two - dimensional computation, the effect of upstream wake on unsteady separated flow field of downstream adjacent vanes was investigated in low - speed axial compressor
摘要利用二維數值模擬研究了低速軸流壓氣機上游尾跡對下游相鄰葉排的非定常分離流場的影響。
