理想和无气泡流态化 作者简介

p>Mooson Kwauk graduated from Univetsity of Shanghai in 1 943 and researched in fluidization under the late Professor Richard WIlhelm at Princeton UniVeTSitv from 1945 t0 1947．He has continued wotking in this field both in the United States and in China，and is now Professor and Director Emetitus of the Institute of Process Eng4neeririg of the Chino．．se Academy 0f Scienccs。to which he was elected Member in 1980．In 1989 he reccived an International Fluidization Award 0f Achievement at the Sixth Interna— tional Fluidization Confefence held in Banff，Canada．     The author postulates an idea“zed system of complete homogeneity that can be used in the 8．nalysis of many engineeting problems，e．g．，     ·  generalized fl uidization with both solids and fluid in flow     ·fluidized leaching and washing     ·SOlids mixing and segregation     ·operation of conical fluidized beds     These problems  arise  in  hydtaulic  classification  according  to particle  size  and den$itv，sedimentation and classification，continuous ion exchange or adsorption，water treatment，fluid—bed electrolysis，and biochemical processes involving granular particles and  supercritical  extraction  of  solid  materials．  Professor  Kwauk  also  expounds alternative bubbleless gas—SOlid contacting systems，e．g．，d讣ute raining particles，fast fluidization，  shallow  fluidized  beds，  and particles  fluidized  under  the  influence  of oscillating  flow--some  of  these techniques  are  already  replacing  their  bubbling predecessors．  He proposes further a method for assessing the fluidizing performance of powdeTS with a view to improving their gas-sohd contacting behavior in the direction of the idea“zed state through particle design． Youchu Li graduated from Tianjin University in 1 962 and was appointed to the Institute of Chemical Metallurgy(now Process Engineeting)of the Chinese Academy of Sciences． He is now a retired professor．  As a researcher and director of the Fluidization Laboratory，he developed correlations for the dynamics of fast fluidization，multi—layer fluidized bed， gas—SOlid mixing，mass and heat transfer in fluidization，and he developed processes  for magnetizing roasting of low- grade and complex iron ores。  calcination of non-metaUic ores，clean coal combustion and pyrolysis and preparation 0f various powdered functional materials．     Professor Li received several awards from the State and the Chinese Academy of Scieaces，and he summaTized in 2008 his more than 40 years’R&D in fluidization in a monograph，“Introduction t0 Fluidization Process Engineering’’(in Chinese)．  In the present pub“cation，he contributed two addenda：one on recent studies on gas-solid flOW and applicatious of fast fluidization and the other on the more recent area of
