纳米级微管流动模型

摘要

Nanoscale microtubules experiment has the characteristics of simple principle and difficult operation complex, because the micro-scale flow is rare, regular flow meter is not suitable for this experiment. TE and Ewart al microtubules flow calculation model contains the experimental experience factor, and the experimental factor is difficult to ensure, as the result, flow accuracy is affected. Combining gas state equation and kinetic equation, a new micro tube flow model was established, the results showed that the new micro pipe flow equation with TE and Ewart al experimental data error was 2. 3%, the flow equation showed that in the nanoscale pore formation temperature, gas viscosity was inversely proportional to flow, provided a new train of thought for dense aerosols of nanoscale pore gas migration regularity study.%纳米级微管实验具有原理简单操作复杂的特点，由于微尺度下的流量极少，常规的流量测试计已经无法适用于该类实验。 TE和Ewart al的微管流量计算模型中含有实验经验因子，且实验因子取值困难，造成了流量精确性受到影响，本文结合气体状态方程及分子运动方程建立了新的微管流动模型，结果表明：新的微管流动方程与TE和Ewart al实验数据误差为2.3%，该流动方程表明在纳米级孔喉中地层温度、气体粘度与流量呈反比，为致密性气藏的纳米级孔喉气体运移规律研究提供新的思路。
