Application of Hydrodynamic Cavitation in Environmental Engineering

Informationen zum Autor Janusz Ozonek , a graduate of Silesian Technical University in Gliwice was specializing in the scope of chemical engineering in the fields close to the problems of environmental protection. After the studies he worked in the following research institutes: Inorganic Chemistry Research Institute in Gliwice and Organic Industry Institute in Warsaw. For the next 8 years he worked in the industry in the Company of Chemical Reagents in Lublin. He has been connected with Lublin University of Technology since 1980. In this University he started an intensive research on the ozone synthesis process and improvement of the phenomenological description for this process in the plasma-chemical reactor. The research constituted the basis for the doctoral dissertation, defended at the Chemical Department of the Silesian Technical University in Gliwice. The development of the model of temperature distribution in the ozonizer depending on the hydrodynamic parameters and power supply was also an important achievement resulting from the conducted research. Most of the works of Janusz Ozonek are interdisciplinary. The chemical ozone synthesis process itself, along with running the processes in the environment of low-temperature plasma require an approach from the side of physical elementary processes and is purposeful for the environmental engineering. Janusz Ozonek is an author or co-author of 5 books, over 40 papers published in technical magazines and over 80 papers presented on the scientific and technical symposiums and conferences both national and international. The subject of the papers is focusing on environmental protection and is mainly connected with the issue of reducing the energy consumption in the process of ozone synthesis and its usage in eco-technologies. He is a member of the International Ozone Association, a member of the Committee of Low-Temperature Plasma Chemistry of the Lublin department of the Polish Academy of Sciences, a member-correspondent of Lublin Science Society and a member of Polish Chemical Society. Zusammenfassung Containing the state-of-the-art in hydrodynamic cavitation, the book consists of two parts. The first part presents the physical basis of cavitation and a systematic classification of various kinds of cavitation and their formation sources. Special attention is paid to a group of factors that promote cavitation formation in natural liquids. A general model of cavitation is formulated as well as a sub-model describing dynamics of the formation, development and collapse of cavitation bubbles. The sub-model also includes effects of cavitation bubble occurrence on the liquid in the direct vicinity of bubbles. Finally, part one also includes a thermodynamic hydrocavitation model of water containing cavitation nuclei (natural waters). The second part deals with the application of hydrodynamic cavitation effects to advanced oxidation of substances that pollute the natural environment. Results of laboratory experiments on the application of cavitation effects to decompose selected organic compounds which hardly undergo biodegradation are presented, as well as a concept of the cavitation phenomenon application on an industrial scale. Application of Hydrodynamic Cavitation in Environmental Engineering will be useful to professionals dealing with the design and practical application of hydrocavitation reactors, and to academics in environmental engineering.

Cavitation is a phenomenon that commonly occurs in many areas of technology. It accompanies liquids flowing in channels of characteristically variable geometry. There are cases when cavitation effects are undesirable as they may cause damage to fluid-flow subassemblies of machines and devices. On the other hand, in environmental protection technology cavitation effects appear to be very useful in supporting chemical processes, in particular when applied in technologies of treatment/decomposition of substances that are harmful for humans and their immediate environment. Containing the state-of-the-art in hydrodynamic cavitation, the book consists of two parts. The first one presents the physical basis of cavitation , and a systematic classification of various kinds of cavitation and their formation sources. Special attention is paid to a group of factors that promote cavitation formation in natural liquids. A general model of cavitation is formulated as well as a sub-model describing dynamics of the formation, development and collapse of cavitation bubbles.
