The calculation method of viscosity and thermal conductivity of natural gas under low temperature is discussed.

论述了低温条件下天然气黏度和热导率的计算方法。

Since continuum hypothesis is still valid for liquid flow in microchannels with hydraulic diameter at about 100 micro-meters, a turbulence convection heat transfer model for single-phase liquid flow in microchannels is established, in which wall surface roughness viscosity is introduced.

分析表明水力直径为100μm左右的微管道内单相液体流动仍满足连续介质假设，引入粗糙度粘性系数，建立了微管道内单相液体湍流对流换热模型，并采用3维有限容积法进行了数值计算，将计算结果与实验结果进行了对比。

The results show that the increasing Marangoni number will lead to more nonlinear distribution of temperature field, but streamfunction of the cell center; vorticity on the wall and peak value of velocity diminish first, then increase, finally lose stability. The thermocapillary convection in the whole liquid zone appears to get stronger along with the augmentation of Prantal number. The effect of increasing of Biot number on temperature and flow fields is not obvious although the convection is strengthened a little. As increasing the aspect ratio A, thermocapillary convection induced by temperature gradient and liquid viscosity becomes stronger.

结果表明：温度场的非线性分布随着Ma数的增大而加剧，但对流涡胞中心流函数、壁面涡量和轴向、径向速度峰值并不象温度场随着Ma数的增大而单调增大，而是先减小，然后增大，最后失稳，表明Ma数对热毛细对流的影响比较复杂，针对不同的物理模型，会导致完全不同的流态；Pr数愈大，流体的热扩散能力在粘性扩散与热扩散能力之比中愈占支配地位，当Ma数一定时，热毛细对流随Pr数的增大在整个液体区域内有增强的趋势；Bi数增大，热毛细对流有所增强，但不甚明显；A的增大使得由温度梯度和流体粘性诱导的热毛细对流随之增强。
