Research Using Computational Fluid Dynamics Featured In September Water Environment Research

Annual Literature Review Also Free Online

According to new research published in the September 2014 issue of Water Environment Research (WER)—the popular journal published by the Water Environment Federation (WEF)—the best plunger mixers were found to behave about the same as the conventional draft-tube mixers. The research, conducted by Robert Meroney and Robert Sheker, is this month’s featured article in the journal's open-access program.

“One of the essential ingredients in a successful biological process is adequate mixing and contact. In this issue, Meroney and Sheker tackle the simulation of vertical mixing in completely mixed anaerobic digesters,” said WER editor-in-chief Tim Ellis. “Using computational fluid dynamics, draft tube mixers and vertical linear plunger mixers were compared with respect to active volume and unit power requirements. In general, conventional draft tube mixers were demonstrated to perform as well or better than many of the vertical mixer configurations.”

Formerly available to subscribers only, selected WER articles such as this one are available free to the public on a monthly basis through an open-access program.

In addition to the monthly free article, WER's annual Literature Review is also open access. The project collects a year's worth of developments on more than forty topics, ranging from wet weather to environmental law in a convenient package. The document, which is over a thousand pages, can be accessed via CD-ROM (included in the September issue) or online.

Published since 1928, WER features peer-reviewed research papers and research notes, as well as state-of-the-art and critical reviews on original, fundamental, and applied research in all scientific and technical areas related to water quality, pollution control, and management. Originally known as the Sewage Works Journal, WER is available in both print and online formats and receives approximately 300 new research submissions each year.
