Handbook of Hydraulic Resistance, 2nd Edition

Abstract

The notion of reviewing an engineering handbook has never been appealing to me. This reviewer has always felt that in most engineering handbooks the material content is too compressed and with poor emphasis on fundamentals. They are usually useful if you want to relearn a forgotten topic, or to understand the operation of an engineering device, or to look up equations and physical properties necessary in design calculations. It has been a very delightful surprise to find out that the Handbook of Heat and Mass Transfer does not fit that notion. The main thrust of this new engineering handbook is the understanding of the fundamentals of transport phenomena. The editor states in the preface that the handbook is aimed at unifying heat and mass transport concepts for the practicing engineer. I believe that the editor has accomplished his goal and more. The editor has enlisted the services of more than one hundred specialists in the field of heat and mass transfer. These specialists have done an excellent job in presenting heat and mass transfer in a manner easy to follow by a stranger to the field and pleasant to read by anyone familiar with the subject. Every chapter opens with an introduction from which the reader obtains a clear picture of the chapter content and concludes with an extensive bibliography. The treatment in each chapter is comprehensive, with minimum redundancy, with hardly an overlap between chapters, indicating a superb editing effort. The work is divided into two volumes. Volume 1: Heat Transfer Operations, contains two sections. The first section, "Heat Transfer Mechanisms," devotes twenty chapters to discussions of principles and applications of transport phenomena. The reader is guided through fundamental and interesting topics such as heat flux in the Benard-Rayleigh problem, natural convection in evaporating droplets, heat flux measurements, forced-convection boiling in uniformly heated channels, etc. In addition, several chapters are devoted to more recent areas of research. The second section, "Industrial Operations and Design," provides 23 chapters on critical unit operations involving heat exchangers, drying operations, combustion, and heat transfer problems in specialized reactors. Volume 2: Mass Transfer and Reactor Design emphasizes multi-component mass transfer in nine chapters. Section II, "Distillation and Extraction," contains eight chapters with emphasis given to design-related problems. Section III, "Multiphase Reactor Systems," devotes 15 chapters to various types of reactors of industrial importance. Section IV, "Special Applications and Reactor Topics," provides five chapters on the subjects of industry crystallization, thermal diffusion columns, parametric pumping, and some other special topics of interest. Overall, the handbook is well written, it covers a wealth of material, and is well produced. I strongly recommend the handbook to anyone working in heat and mass transfer.

Structural-hydraulic test of the liquid metal EURISOL target mock-up

“…Experimental data included results for both configurations, without and with flow vanes (referred to here as METEX 1.1 and METEX 1.2, respectively). Even though the configuration analysed ( [9], configuration no. 5) does not exactly match those of our design, good agreement between the estimated and measured pressure losses was found.…”

“…The total pressure drop in the mock-up was measured as well as calculated by using well-known empirical correlations and experimental data [9] for similar flow configurations. The calculated pressure loss is directly compared with the experimental results in Fig.…”

Distributor effects near the bottom region of turbulent fluidized beds

“…The installation of two grids close to each other should not lead to an increase in flow resistance, but rather results in a grid of double thickness in the flow direction [19].…”

“…For the entrance into a straight tube through a perforated plate with thick orifices Idelchik [19] gives: …”

Investigating the interactions between an atmosphere and an ejecta curtain: 2. Numerical experiments

“…Published data link hydraulic resistance to the thickness, porosity, and dominant particle size comprising a porous boundary, and atmospheric properties such as viscosity and density [Idelchik, 1994]. Such results can be combined with appropriate atmosphere and cratering models [e.g., Maxwell, 1977;Schultz and Gault, 1979;Orphal et al, 1980;Housen et al, 1983] to determine the length of the impermeable portion of the curtain and the time when it transitions from impermeable to permeable.…”
