《理想和无气泡流态化》主要内容:When fluid来自ization was first employed industrially,e.g., in the Winkler gasifier, we had only the bubbli应热草听引顾改ngfluidiz食行磁间参倍能ed bed as shown 犯in the middle diagram of thefigure, in which gas bypasses as bubbles, thus leadingto poor solid-gas contact and incurring large pr360百科essuredrop.

Mooson Kwauk graduated from University of Shangha请伟屋都走孙龙试背周i in1 943 and resea代求翻度地rched in fluidization under the late ProfessorRichard Wilhelm at Princeton Universi载路家ty from 1 945 to1947.He has continued work序斯者的限雨凯且绍终ing in this field both in theUnited States and in China,and iS now Professor andDirector Emeritus of the Institute of Process Engineering ofthe Chinese Academy of Sciences,to which he was electedMember in 1980.In 1989 he rec名率仅村千阳及题夜eived an InternationalFluidization Award of Achievement at the Sixth 紧建充轴盟International Fluidization Conference held in Banff,Canada.
The author postulates an idealized system of completehomogeneity that can be used in the analysis of many engineering problems,e.g.,
·generalized fluidization with both solids and fluid in flow
·fluidized leaching and washing
·solids mixing and segregation
·operation of conical fluidized beds
These problems arise in hydraulic classification according to particle size anddensity,sedimentation and classification,continuous ion exchange or adsorption,watertreatment,fluid-bed electrolysis,and biochemical processes involving granular particlesand supercritical extraction of solid materials.Professor Kwauk also expoundsalternative bubbleless gassolid contacting systems,e.g.,dilute raining particles,fastfluidization,shallow fluidized beds,and particles fluidized under the influence ofoscillating flowsome of these techniques are already replacing their bubblingpredecessors.He proposes further a method for assessing the fluidizing performance ofpowders with a view to improving their gas-solid contacting behavior in the direction ofthe idealized state through particle design.
Youchu Li graduated from Tianjin University in 1962 andwas appointed to the Institute of Chemical Metallurgy(nowProcess Engineering)of the Chinese Academy of Sciences.He is now a retired professor.As a researcher and directorof the Fluidization Laboratory,he developed correlations forthe dynamics of fast fluidization,multilayer fluidized bed,gas-solid mixing,mass and heat transfer in fluidization,andhe developed processes for magnetizing roasting of low-grade and complex iron ores,calcination of non-metallicores,clean coal combustion and pyrolysis and preparation ofvarious powdered functional materials.
Professor Li received several awards from the State and the Chinese Academv ofSciences,and he summarized in 2008 his more than 40 years'R&D in fluidization in amonograph,"Introduction to Fluidization Process Engineering"(in Chinese).In thepresent publication,he contributed two addenda:one on recent studies on gas-solid flowand applications of fast fluidization and the other on the more recent area of magnetoflu-idization,both involving not a few of his own innovations.
