According to the experimental data, it is found that the circumferential diffierence of heat transfer characteristics occurres due to the effects of thermal acceleration and buoyance in the inclined smooth tube at supercritical pressure.

实验结果表明：在超临界压力区域，倾斜光管内可能由于受到热加速度和浮力的综合作用，倾斜光管传热特性沿周向是不均匀分布状态，通常管内顶部的壁面温度比底部高，在大比热区发生传热恶化和传热强化的现象，低质量流速和高热负荷条件下会发生传热恶化现象，高质量流速下会发生传热强化，避免壁温发生飞升；内螺纹管内的传热特性在不同焓值区域表现不同，在远离拟临界焓值的低焓值区域和高焓值区域，呈现出相似的规律，而在接近拟临界焓值区域时，传热得到强化。

By using grand canonical ensemble Monte Carlo method, machanism for the adsorption of methane in single wall carbon nanotubes at 74.05 K has been investigated. It is found that the adsorption of methane in smaller SWNTs, whose diameters are 1.22nm and 1.632nm, exhibits "pore filling" behavior. In contrast, for the SWNTs of diameter larger than 2.04nm, capillary condesation takes place.
