Electronic Airflow through Electrical Enclosures At one point in my engineering career I was tasked with developing estimates of the thermal conditions within a family of electronic enclosures. Our senior engineering staff resisted introducing a CFD package to support these analyses. In response, I used this book to develop airflow "circuits" within our equipment by defining the flow resistances within connected definable regimes within these enclosures. With a bit of thermodynamics and a mathematical performance model for our variable speed fan set, I was able to produce very good results running the flow path studies on a math package. I set up the math package to iterate to a solution, knowing the distribution of heat generation within various regimes of the enclosures (the general locations of the hot parts). Among other things, the iterative process adjusted variable speed fan performance, via the model, accordingly. The regime specific flow resistance equations were borrowed directly from this book. This book was a godsend in that analysis. | ||
VERY comprehensive guide for hydraulic engineers This book is essential for anyone who does detailed hydraulic calculations for a living and is looking for a comprehensive guide to estimating minor losses or other non-standard frictional losses. The number of configurations listed for tubes, fittings, valves, bends, valves and wyes is astounding; light years beyond any textbook or reference guide I have seen. For the most part, the Design Guide cuts out a lot of the PhD-type derivations and gets to the point, hence it's title. One drawback is that the nomenclature used for formulas is not the standard used in the U.S. (i.e. "F" is used for cross-sectional area). Also, the presentation of material tends to be math intensive and detail oriented, so be prepared to do some reading before jumping right in. This is not a book for the faint of heart but, once I got used to the setup, the book has proven to be an invaluable tool in my work. | ||
The most comprehensive book on loss coefficients so far. I am an instrument engineer. I calculate trim loss coefficient of control valves often. I use three books: (1) Crane Technical Publication 410, (2) Blevins Applied Fluid Dynamics Handbook, and now (3) Fried and Idelchik Flow Resistance: A Design Guide for Engineers. The third one covers tons of flow geometries more than the first two, with many tables, diagrams, and graphs, and is easy to use. The only not-so-good about this book is that it uses unfamiliar symbols and nomenclature that we don't use in N. America, and it does not give derivations of the equations used. The later issue is understandable due to the huge number of flow geometries described. But one can derive the loss coefficient equations for many flow geometries based on normalization and basic geometries desbribed in Crane Technical Publication 410 and then cross check the results against those shown in this Fried and Idelchik book. The Blevins book is for advanced users, and is more accurate since theory is given. Regarding the first issue, it is not a big problem because the nomenclature is fairly consistent in this book. A 5-star book for all engineers who deal with fluid flows! except it is pricy. I hope this helps. | ||
Don't design HVAC systems without it! Although lacking as much explanation as featured in Idelchik's Handbook of Hydraulic Resistance, this book contains much of (if not all) the same informative figures and design data frequently referenced by popular engineering and industry literature such as the ASHRAE (American Society of Heating, Refrigeration, and Air-conditioning Engineers) Handbook series. This book is an excellent resource for engineers familiar with fluid dynamics who want to better estimate aerodynamic or fluidic performance of their products and/or systems. For example, the book eliminates risky guess-work by providing frictional loss coefficients for a broad and deep variety of commonly (and uncommonly) used air passage geometries, obstructions, and other sources of flow resistance. The reader would be hard-pressed to find the same information in a similarly compact and convenient format. Not only that, but Idelchik's work is, by-and-large, a presentation of actual test data which, despite being a few or more decades old, is still considered extremely valuable today. | ||
