The experimental results of the flow characteristics of the mmc heat sink indicate that the critical reynolds number signifying the transition from laminar flow to turbulent flow is in advance ; under the same experimental conditions, the variation in entrance direction of the microchannel inlet and outlet has little effect on the microchannel ; the experimental values of the friction factor of the de - ionized water in a microchannel agree well with those calculated using the theoretical laminar formula ; furthermore, a comparison of the experimental results and simulation results shows that navier - stokes equation and rng - turbulence model can be used to model the laminar and turbulence flow regions in a microchannel ; meanwhile, the correlations of the flow resistance in the turbulent flow regions for the de - ionized water as the working fluids are obtained from experiments
對歧管式單通道熱沉流動特性的研究結果表明，微通道內流體流態由層流向紊流轉變的臨界雷諾數提前;改變流體的進出口方向對熱沉總壓降造成的影響很小;摩擦系數的實驗值與理論值較接近;數值模擬結果能夠與實驗值較好吻合;並由實驗給出了紊流區流動阻力的實驗關聯式。此外，選用十二烷基硫酸鈉（ sodiumdodecylsulphate ， sds ）以及烷基多糖苷（ alkylpolyglycoside ， apg ）作為減阻添加劑，研究了表面活性劑添加對微通道流動特性的影響。 -
The numerical analysis indicates that that the multi - longitudinal vortex flow in tubes can markedly enhance both the laminar and turbulent heat transfer with less additional increase of flow resistance
結果表明，管內多縱向渦對層流和湍流換熱的強化效果顯著而流阻增加較少，具有優良的綜合強化換熱性能。 -
The transition to the turbulent flow happened when the reynolds numbers ( based on the height of mini - channel ) were between 1200 and 1400. and it was found that the critical reynolds numbers became larger when the friction - resistance factor got smaller
