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。Owing to the interfacial cracking which occurs under higher applied load conditions, the composite with high content of tib _ 2 phase exhibited a transition from mild wear to severe wear over the applied load range from 10 n to 80 n. under moderate applied load, increasing the sliding speed caused a decrease in wear rate and friction coefficient of the in - situ composites because the formation of a protective oxide film occurred on the sliding surface and the hardness of the subsurface layer was maintained due to reinforcement of tib2 nanoparticles in the cu matrix
隨著載荷的增加， cu -納米tib2原位復合材料的磨損率和摩擦系數增加；由於在較高載荷下發生表面開裂，高含量的tib2相增強原位復合材料發生了由輕度磨損向嚴重磨損形式的轉化。在中等載荷下由於表面保護性氧化膜的形成和基體中納米tib2相的存在使復合材料具有良好的抗軟化能力， cu -納米tib2原位復合材料的磨損率和摩擦系數隨著滑動速度的增加而下降。
