| 1 | Observation on rapid transient explosive boiling under pulsed-laser heating显示文摘Using various kinds of liquids (pure acetone, binary mixtures in various volume fractions of ethanol and acetone) as working liquids, the experiments of rapid transient explosive boiling induced by pulsed-laser irradiation are carried out. The temperature field on a microsecond scale is measured, and the behavior of bubbles is observed and captured by a microscopic camera system. The extreme characteristics that differ from those in normal boiling are clearly revealed. The influence of working liquid species, volume fraction of the mixture, nanoparticles added in the working liquid, and the laser irradiation parameters on the boiling behavior are also studied. | HUAIXiulan DONGZhaoyi LIUDengying ZHANGXing | 2003 | Progress in Natural Science:Materials International2003，13，5： | 2 |
| 2 | DPL Model Analysis of Non-Fourier Heat Conduction Restricted by Continuous Boundary Interface显示文摘Dual-phase lag (DPL) model is used to describe the non-Fourier heat conduction in a finite medium where the boundary at x=0 is heated by a rectangular pulsed energy source and the other boundary is tightly contactal with another medium and satisfies the continuous boundary condition. Numerical solution of thes kind of non-Fourier heat conduction is presented in this paper. The results are compared with those predicted by the hyperbolic heat conduction (HHC) equation. | JinangFangming LiuDengying | 2001 | Journal of Thermal Science2001，10，1： | 1 |
| 3 | Experimental study on the explosive boiling in saturated liquid nitrogen显示文摘Studies on the heat-transfer characteristics of liquid nitrogen (LN 2) have received increasing attention. When there is a transient high heatflux input to the LN 2, explosive boiling may take place. In this paper, using the high-power short-duration pulsed laser heating method and the high-speed photography technology, the experimental result of explosive boiling in saturated LN 2 is illustrated; and the two exclusive characteristics of explosive boiling in LN 2: changeover time and the relative long-time adherence of the bubble cluster to the surface, are investigated. | DONGZhaoyi HUAIXiulan LIUDengying | 2005 | Progress in Natural Science:Materials International2005，15，1： | 1 |
| 4 | Experimental study of thermally-driven micro-pump using stepped laser显示文摘The stepped pulse-laser is used to heat the fluid in a micro-tube with the diameter less than 1 mm, and a phase change and a directional flow of the fluid are induced. Based on many experimental observations, the mechanism of thermally-driven MEMS is studied and the technical approaches of the efficient and steady thermally-driven flow is given. The experimental results show that the hypostasis of the thermally-driven micro-pump is a kind of erratic liquid-vapor two-phase flow, and the liquid movement and the change rate of the pressure is closely related to the bubbles’ behavior in the micro-tube. | ZHOUHong HUAIXiulan LIHuazhi LIUDengying MENGQun | 2004 | Progress in Natural Science:Materials International2004，14，8： | 0 |
| 5 | Study of rapid transient explosive boiling under short-pulsed laser heating显示文摘Using acetone, ethanol, water and acetone-water mixture as test liquids, the rapid transient explosive boiling (RTEB) taking place under short-pulsed laser heating is observed in experiment. The behaviors of temperature variation are investigated via transient temperature measurement. The vapor bubble behaviors of RTEB are captured by high-speed photography, and the difference between RTEB and normal boiling is analyzed. The boiling heat transfer of RTEB is also discussed. It shows that the character of RTEB is far different from normal boiling. | JINRenxi HUAIXiulan LIUDengying | 2004 | Progress in Natural Science:Materials International2004，14，8： | 0 |
