论文摘要
1d二氧化硅纳米氧化硅纳米通道的高度为59 nm，87 nm，124 nm和1015 nm的实验用于估计水的分离压力，发现水的压力高达〜1.5 mpa，而随着通道高度的增加，水的高度高约1.5 mpa。在计算流体动力学中实现并验证了由实验衍生数据的曲线拟合产生的这种关系。该方法将实验性纳米级物理学整合到连续模拟中，从而实现了对各种现象的数值研究，其中不结合压力起着重要作用。
Experiments of water wicking in 1D silicon-dioxide nanochannels of heights 59 nm, 87 nm, 124 nm and 1015 nm are used to estimate the disjoining pressure of water which was found to be as high as ~1.5 MPa while exponentially decreasing with increasing channel height. Such a relation resulting from curve fitting of experimentally-derived data was implemented and validated in computational fluid dynamics. This methodology integrates experimental nanoscale physics into continuum simulations thus enabling the numerical study of various phenomena where disjoining pressure plays an important role.
