| 1 | Numerical study on onset of oscillatory thermocapillary flow in rectangular liquid pool显示文摘Thermocapillary flow in a rectangular liquid pool of large Prandtl fluid(Pr=105.6) is numerically studied in microgravity.Oscillatory thermocapillary flow arises when the imposed temperature difference between the sidewalls exceeds a critical value.The fluctuations of the oscillatory flow,accompanied by the propagation of the hydrothermal wave from the cold sidewall to the hot one,are much smaller than the time-averaged velocity and temperature fields.The corresponding disturbance cells arise in the centre of the liquid pool initially,and extend to the whole region with the increasing imposed temperature difference.The present study reveals the different characteristics of the oscillatory themocapillary flow in the rectangular liquid pool as compared to the cases in other configurations. | HU WenRui,TANG ZeMei & LI Kai Key Laboratory of Microgravity(National Microgravity Laboratory),Institute of Mechanics,Chinese Academy of Sciences,Beijing10090,China | 2010 | Science China(Technological Sciences)2010，53，4： | 2 |

| 4 | Period-doubling bifurcations of the thermocapillary convection in a floating half zone显示文摘This study experimentally explored the fine structures of the successive period-doubling bifurcations of the time-dependent thermocapillary convection in a floating half zone of 10 cSt silicone oil with the diameter d0=3.00 mm and the aspect ratio A=l/d0=0.72 in terrestrial conditions.The onset of time-dependent thermocapillary convection predominated in this experimental configuration and its subsequent evolution were experimentally detected through the local temperature measurements.The experimental results revealed a sequence of period-doubling bifurcations of the time-dependent thermocapillary convection,similar in some way to one of the routes to chaos for buoyant natural convection.The critical frequencies and the corresponding fractal frequencies were extracted through the real-time analysis of the frequency spectra by Fast-Fourier-Transfor-mation(FFT).The projections of the trajectory onto the reconstructed phase-space were also provided.Furthermore,the experimentally predicted Feigenbaum constants were quite close to the theoretical asymptotic value of 4.669 [Feigenbaum M J.Phys Lett A,1979,74:375-378]. | AA Yan,LI Kai,TANG ZeMei,CAO ZhongHua & HU WenRui National Microgravity Laboratory,Institute of Mechanics,Chinese Academy of Sciences,Beijing 100190,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，9： | 1 |

| 6 | Recent Progress of Graphene Fiber/Fabric Supercapacitors:From Building Block Architecture,Fiber Assembly,and Fabric Construction to Wearable Applications显示文摘High-performance fiber-shaped power sources are anticipated to considerably contribute to the continuous development of smart wearable devices.As one-/two-dimensional(1D/2D)frameworks constructed from graphene sheets,graphene fibers and fabrics inherit the merits of graphene,including its lightweight nature,high electrical conductivity,and exceptional mechanical strength.The as-fabricated graphene fiber/fabric flexible supercapacitor(FSC)is,therefore,regarded as a promis-ing candidate for next-generation wearable energy storage devices owing to its high energy/power density,adequate safety,satisfactory flexibility,and extended cycle life.The gap between practical applications and experimental demonstrations of FSC is drastically reduced as a result of technological advancements.To this end,herein,recent advancements of FSCs in fiber element regulation,fiber/fabric construction,and practical applications are methodically reviewed and a forecast of their growth is presented. | Tuxiang Guan Zemei Li Dianchun Qiu Guan Wu Jian Wu Liping Zhu Meifang Zhu Ningzhong Bao | 2023 | Advanced Fiber Materials2023，5，3： | 0 |
| 7 | Influence of the heating rate on the critical Marangoni number of oscillatory thermocapillary convection in the floating half zone显示文摘In the present study, numerical simulations were conducted on thermocapillary convection in floating half zones of 5 cSt silicone oil of different scales in comparison with the experimental studies in the microgravity conditions. The effect of heating rate on the marginal instability boundaries is indicated as a possible explanation for the significant quantitative discrepancies between the experimental results in the terrestrial conditions and in the microgravity conditions. | LI Kai TANG ZeMei HU WenRui | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，1： | 0 |
