| 4 | Design,fabrication and experimental research for an electrohydrodynamic micropump显示文摘This paper presented a novel electrohydrodynamic (EHD) micropump based on MEMS technology. The working mechanisms and classification of EHD micropump were introduced. The fabrication process of EHD micropump was presented with the material selection,optimal design of microelectrode and assembly process. Static pressure experiments and flow experiments were carried out using different fluid and the channel depth. The results indicated that the micropump could achieve a maximum static pressure head of 268 Pa at an applied voltage of 90 V. The maximum flow rate of the micropump-driven fluid could reach 106 μL/min. This paper analyzed the future of combining micropump with heat pipe to deal with heat dissipation of high power electronic chips. The maximum heat dissipation capacity of 87 W/cm2 can be realized by vaporizing the micropump-driven liquid on vaporizing section of the heat pipe. | YU He, YU Jian & MA ChongFang Key Lab of Enhanced Heat Transfer & Energy Conservation, Ministry of Education and Key Lab of Heat Transfer & Energy Conversion, Beijing Municipality, College of Enviromental and Energy Engineering, Beijing University of Technology, Beijing 100124, China | 2010 | Science China(Technological Sciences)2010，53，10： | 6 |

| 6 | Application of the lattice Boltzmann method to electrohydrodynamics: Deformation and instability of liquid drops in electrostatic fields显示文摘It is attractive and meaningful to apply the lattice Boltzmann method (LBM) to electrohydrodynamic (EHD) problems. As an important and fundamental problem in EHD, the behavior of freely-suspended liquid drops subjected to electrostatic fields was simulated with a 2-D LBM by means of the permittiv- ity-density relation proposed by the authors and Peng’s multiphase LBM which can obtain high liquid-to-vapor density ratio and low liquid-phase compressibility. The phenomena and laws of deformation, especially the instable behavior of the liquid drops were well simulated. And two important critical parameters, i.e. the critical permittivity ratio and the critical electric-field strength were obtained. These results agree with the corresponding theories and experiments. The simulations show the particular advantages and potential of the LBM in studying multiphase electrohydrodynamic problems. | HUANG WeiFeng LI Yong LIU QiuSheng | 2007 | Chinese Science Bulletin2007，52，24： | 3 |

| 9 | Bifurcation mechanism of interfacial electrohydrodynamicgravity-capillary waves near the minimum phase speed under ahorizontal electric field显示文摘We investigate the evolution of interfacial gravity-capillary waves propagating along the interface be-tween two dielectric fluids under the action of a horizontal electric field.There is a uniform backgroundflow in each layer,and the relative motion tends to induce Kelvin-Helmholtz(KH)instability.The com-bined effects of gravity,surface tension and electrically induced forces are all taken into account.Underthe short-wave assumption,the expansion and truncation method of Dirichlet-Neumann(DN)operatorsis applied to derive a reduced dynamical model.When KH instability is suppressed linearly by a consider-ably large electric field,our numerical results reveal that in certain regions of parameter space,nonlinearsymmetric traveling wave solutions can be found near the minimum phase speed.Additionally,the de-tailed bifurcation structures are presented together with typical wave profiles. | Gexing Xu Zhi Lin | 2021 | Theoretical & Applied Mechanics Letters2021，11，2： | 0 |
