| 1 | Mechanism of energy limit equilibrium of rock burst in coal mine显示文摘随采矿深度的增加,在煤采矿上冲破的岩石的效果正在变得越来越明显,岩石爆炸机制变得越来越复杂。来自许多国家的学者提出了不同机制,但是没有人把合理解释给了冲破的岩石的机制。在这份报纸,基于精力理论,我们学习了矿岩石冲破了的煤的精力限制平衡(ELE ) 。有冲破的岩石的煤缝接被划分成精力限制平衡地区(ELEZ )(A) 和有弹性的地区(B) ;我们也决定了岩石爆炸发生的位置,包括煤缝接的房顶和地板;另外,我们导出在限制宽度和冲破的岩石的出现机制之间的 ELEZ 和数学关系的限制宽度:精力差别功能(EDF ) , w (x)= wj wp 一阶的衍生物 w (x) ,是不到 0。EDF 因此是 monotonically 减少的功能。精力差别功能的图也被决定,通过哪个我们分析了岩石的出现机制爆炸。 | Wang Jiong Yan Yubiao Jiang Zhengjun Qi Ping Chen Chen | 2011 | Mining Science and Technology2011，21，2： | 4 |
| 2 | On Aircraft Lift and Drag Reduction Using V Shaped Riblets显示文摘Reducing drag during take-off and nominal(cruise)conditions is a problem of fundamental importance in aeronautical engineering.Existing studies have demonstrated that v-shaped symmetrical riblets can effectively be used for turbulence control,with those with dimensionless depth h+=15 and dimensionless width s+=15 having the best drag reduction effect.In the present study,experimental tests have been conducted considering two models of the same size,one with smooth surface,the other with v-shaped riblets of the h+=15 and s+=15 type.The results show that for an angle of attack in the 8°~20°range(take-off stage),the maximum lift coefficient can be increased by 22%.For angle of attack between 8°and 14°,a drag reduction effect can be produced using riblets,which increases with the Reynolds number,leading to a decrease in the drag coefficient maximum of 36%.Flow visualization experiments have been carried out by means of Laser Induced fluorescence. | Zihai Geng Jinsheng Cai Yubiao Jiang Weiguo Zhang | 2021 | Fluid Dynamics & Materials Processing2021，17，5： | 0 |
