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。

Amp and adp were not significantly changed throughout the experiments, pa tended to decreased with the increases of concentrations of pollutants, nitrite - na and sodium polyphosphate could decrease atp, while methyl parathion showed a disordered atp change. aec, atp / adp and total adenylate content solely could be poor health condition markers. pa and atp are proposed as direct health condition markers of an organism to environmental stress
