Numerical Simulation of Pulsed Liquid Fluidized Bed and Its Experimental Validation

The pulsed liquid fluidized bed was studied using numerical simulation and experimental methods, The area-averaged two-fluid model (TFM) was used to simulate the pulsed fluidization. The bed expansion and collapse processes were simulated first and the phenomena obtained from the calculation were consistent with our previous experiments and observations. In the pulsed fluidization, the variation of bed height, the variations of particle velocity and concentration distribution were obtained and analyzed. Experiments were carried out to validate the simulation results. The pressure variation with time at different locations was measured using pressure transducers and compared with the simulated results. The variations of bed height and particle concentration distribution were recorded using a digital video camera recorder. The results were consistent with the simulation results as a whole.

李敏华院士传略

<正>李敏华,女,1917年11月2日出生于江苏省吴县(苏州市)的职员家庭。母亲思想比较开明,毕业于杭州女子师范中学,支持李敏华姐妹自小读书。1925年,李敏华刚到上海不久便发生了"五卅惨案",上海滩上,英国巡捕随便打杀中国人,外国军舰在黄浦江上耀武扬威的种种事实,给少年的李敏华留下深刻的印象。1931年,日本侵略军侵略我国东北三省。李

光学领域里的一对奇葩——介绍2005年诺贝尔物理学奖

2005年诺贝尔物理学奖授于了光学研究领域里的两项原创性工作：1963年美国物理学家罗伊·格劳伯（R．J．Glauber 1925～）提出的“相干性量子理论”，以及1983年美国物理学家约翰·霍尔（J．L．Hall．1934～）和德国物理学家特奥多尔·亨施（T．W．Hansch．1941～）利用激光的特性对精确测量技术所作的发展。近些年来诺贝尔物理学奖频频惠顾光学研究领域。如2001年诺贝尔物理学奖授予了从事玻色一爱因斯坦凝聚的相关研究、1997年诺贝尔物理学奖授予华裔科学家朱棣文从事的激光冷却和俘获原子
