| 1 | Droplet Motion and Phase Change Model with Two-Way Coupling显示文摘The droplet interacts intensively with surrounding gas when moving and evaporating in the gas,of which the mutual effects of the gas and the evaporating droplet need to be taken into account.For the typical droplet model,the gas parameters are usually considered as that at infinity and the local parameter variation surrounding the droplet is neglected,consequently leading to some discrepancies.This research tries to develop a new moving droplet phase change model with two-phase coupling which characterizes the local parameter variation of gas phase surrounding the evaporating droplet.Firstly,the interaction mechanism of two phases is presented based on the droplet evaporation phenomena.Then,the droplet motion and phase change model is developed through the theoretical derivation.Subsequently,the analysis of the evaporation characteristics of the injected droplets in the hot air is conducted to simulate the operation process of the containment spray system in the nuclear power station.The numerical simulation indicates the refined droplet model is more capable for precise prediction of the situations with large quantities of evaporating droplets and with intensive interactions between two phases. | ZHAO Fulong LIU Qianfeng YAN Xiao BO Hanliang ZENG Chen TAN Sichao | 2019 | Journal of Thermal Science2019，28，4： | 2 |

| 8 | A Selective‑Response Hypersensitive Bio‑Inspired Strain Sensor Enabled by Hysteresis Effect and Parallel Through‑Slits Structures显示文摘Flexible strain sensors are promising in sensing minuscule mechanical signals,and thereby widely used in various advanced fields.However,the effective integration of hypersensitivity and highly selective response into one flexible strain sensor remains a huge challenge.Herein,inspired by the hysteresis strategy of the scorpion slit receptor,a bio-inspired flexible strain sensor(BFSS)with parallel through-slit arrays is designed and fabricated.Specifically,BFSS consists of conductive monolayer graphene and viscoelastic styrene–isoprene–styrene block copolymer.Under the synergistic effect of the bio-inspired slit structures and flexible viscoelastic materials,BFSS can achieve both hypersensitivity and highly selective frequency response.Remarkably,the BFSS exhibits a high gage factor of 657.36,and a precise identification of vibration frequencies at a resolution of 0.2 Hz through undergoing different morphological changes to high-frequency vibration and low-frequency vibration.Moreover,the BFSS possesses a wide frequency detection range(103 Hz)and stable durability(1000 cycles).It can sense and recognize vibration signals with different characteristics,including the frequency,amplitude,and waveform.This work,which turns the hysteresis effect into a'treasure,'can provide new design ideas for sensors for potential applications including human–computer interaction and health monitoring of mechanical equipment. | Qun Wang Zhongwen Yao Changchao Zhang Honglie Song Hanliang Ding Bo Li Shichao Niu Xinguan Huang Chuanhai Chen Zhiwu Han Luquan Ren | 2024 | Nano-Micro Letters2024，16，2： | 0 |
| 9 | Numerical simulation of the Rayleigh-Taylor instability using the MPS method显示文摘In this paper,the two-dimensional Rayleigh-Taylor(RT) instability is directly simulated using the moving particle semiimplicit(MPS) method,which is based on the fully Lagrangian description.The objectives of this paper are to investigate preliminarily the effect of viscosity and finite size domain on the evolution of the RT instability.The simulation results demonstrate that(1) the mushroom-like vortex motions are formed in late time due to fluid viscosity,which give rise to the secondary shear flow instability,(2) the finite thickness of the fluid layer limits the development of the RT instability.The above results are consistent with the experiments and theoretical analyses.Meanwhile,the linear growth rate of the RT instability obtained from the numerical simulation is also in agreement with theoretical analyses.And the nonlinear threshold from the simulation result is comparable with the theoretical estimate.Two stages of the nonlinear evolution of the RT instability are revealed in the numerical simulation,nonlinear saturation and turbulent mixing. | CHENG HuiFang JIANG ShengYao BO HanLiang DUAN RiQiang | 2012 | Science China(Technological Sciences)2012，55，10： | 0 |
