Book Description
In a previous report techniques were described for measuring turbulence and velocity profiles in turbulent shear flows of water and dilute fiber suspensions, and some preliminary results presented. The present report describes subsequent experience with the techniques, and the results of their application to an extended range of flow velocities and an additional wood pulp suspension. The report has two areas of emphasis. The first has to do with some basic facts about turbulence, together with relevant theoretical relations among variables and their implications as regards problems of measurement and analysis. The second relates to the specific -measurements and their significance as regards flowing fiber suspensions. The results confirm and extend the previous conclusions regarding the .mechanism of turbulence and the momentum transfer process in dilute fiber suspensions. In particular, the significance of the combined roles of turbulence and fiber entanglement in diffusion and mixing is examined in detail. The necessity of isolating these roles is discussed and recommendations presented. The procedures employed for data measurement and analysis of the statistically turbulent flow are: analyzed and recommendations made.

Advances in Water Pollution Research
Author: S. H. Jenkins
Publisher: Elsevier
ISBN: 1483186970
Category : Technology & Engineering
Languages : en
Pages : 973
Book Description
Advances in Water Pollution Research features the 71 papers presented at the Sixth International Conference held in Jerusalem on June 18-23, 1972. These papers were those selected by the Programme Committee of the International Association on Water Pollution Research for discussion at the conference out of the 176 completed papers that were submitted. The topics of the papers in this book include industrial waste water problems, sewage treatment problems associated with solids, ponds, activated, sludge, groundwater pollution, trace metals in water, wastewater virology and microbiology, thermal pollution, and oxygen transfer. This book also provides the text of the discussion on these papers as well as the replies of the authors. This book will be of interest to persons dealing with studies on water pollution and pollution control.
