柱状波纹纳米孔中玻璃态固体氦的可能增强通量

Possible Enhanced Flux of Glassy Solid Helium in Cylindrical Corrugated Nanopores

Chu Kwang Hua, Guang Hua Zhu

摘要:

通过使用玻璃态(氦-)流体模型和边界微扰方法,我们可以获得与Kim和Chan以及Day { \it et al.}制备的样品尺寸相同的波纹粗糙圆柱形纳米孔内的速度场(以及流量;高达二阶)。我们的研究结果表明,在多孔Vycor样品中测量的速度可以通过仔细选择相关参数重现,但在玻璃毛细管中很难获得。

英文摘要:

By using the glassy (helium-)fluid model and boundary perturbation method, we can obtain the velocity fields (as well as the flow rate; up to the second order) inside the wavy-rough cylindrical nanopores which are of the same size as those samples prepared by Kim and Chan as well as Day {\it et al.} Our results show that the velocities measured in porous Vycor samples could be reproduced by carefully selecting relevant parameters but those in glass capillaries are difficult to obtain.
