Heat Exchanger Design Handbook Online: Standard reference on heat exchangers

U-Tube Heat Exchanger

Find It

VCU Libraries has recently acquired a new resource. The Heat Exchanger Design Handbook is a standard reference source for design and other information on heat transfer, heat exchanger and other associated technologies. This online resource is the updated and expanded electronic version of the print. It covers all aspects of heat exchanger design and operation, including the basic design methodology, the associated heat transfer and fluid flow technology and the physical data required for design.

The resource is broken into five volumes. All are searchable simultaneously using keyword or phrase, author or editor:

  • Volume 1 sets the scene to present basic theory of heat exchanger and generic application technology.
  • Volume 2 gives the fundamentals of heat and mass transfer and fluid mechanics.
  • Volume 3 addresses the design of thermal and hydraulic heat exchangers.
  • Volume 4 describes mechanical design of heat exchangers and basic mechanical principles.
  • Volume 5 gives the physical properties

All volumes can be searched simultaneously but the results show the volume from which they were retrieved. For example, a simple search using the phrase “tube exchanger design” produces articles from volume 4 that give the specification and design codes for designing shell and tube heat exchangers,

Faculty and students, will find this resource very useful, particularly for senior design projects.

Merck Index Online: for research and everyday

Find It

Merck Index Online is an authoritative source of information on chemicals, drugs and biologicals. You an search or browse its more than 11,000 monographs (chemical compounds) that can be explored for research and everyday practical purposes. Ideal for quick searches to reveal the properties of compounds and biologicals, Merck Index Online provides identifiers such as CAS Registry Number and structure. It also gives the molecular formula, molecular weight and melting point as well as Trademark names.

Structure search is simplified by the ‘convert’ feature, which allows for inserting a compound name and then converting it to a structure to enable a substructure or exact structure search. It has more than 500 organic named reactions (ONR) which have been recognized and referred to by name within the chemistry community, for example, the Ehrlich-Sachs Reaction (1899). Attached to each ONR are relevant references including that of the original description. All references are from scholarly journals, encyclopedias and handbooks. Apart from properties, all records have appropriate sections that describe them, depending on the type of compound. One example is the “Therapeutic Category” under Classifications, which is useful for identifying uses of compounds and their derivatives in healing, re: Glybuzole – Trademark name – Gludiase as an antidiabetic. The database is further enhanced by its 28 reference tables.

Merck Index Online is valuable to researchers, faculty and students in basic science, chemistry, pharmacy, chemical and life science engineering, biomedical sciences, dentistry, allied health, and medicine. It is also useful for everyday practical purposes such as information on additives or components, nutrients, minerals, and proteins. For example, get all the information for the cooking spice, nutmeg, its uses in flavoring food and beverages, nutmeg oil as a fragrance in soaps, detergents, creams, lotions, perfumes, and candles.

What are “standards” and how to get them

512px-Prototype_kilogram_replica

Standards are documents detailing specifications researchers adhere to in designing new products, systems and processes in order to ensure minimum performance stipulations, safety, consistency and repeatability.

VCU Libraries can provide digital copies of standards usually within one hour of a patron making the request. This standards-on-demand program uses a vendor that supplies standards from organizations and societies including:

  • American National Standards Institute (ANSI);
  • American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE);
  • American Society of Mechanical Engineers (ASME);
  • Society of Automotive Engineers (SAE International);
  • International Organization for Standardization ISO.

In addition, American Society for Testing and Materials (ASTM) Digital Library and IEEE Xplore provide thousands of standards from their respective organizations, and VCU Libraries provides access to these standards without a wait.

How to request standards

Students, faculty and staff can contact Ibironke Lawal (804) 828-8739 or ilawal@vcu.edu.
