Juliusz Bohdan Gajewski worked at the Institute of Environmental Protection Engineering of the Technical University of Wrocław, Wrocław, Poland, from 1976 to 1980 as a doctoral candidate. He was involved in the fields of static electricity, non-intrusive metrology of electric charge in pneumatic transport, protection against fire and explosion hazards, and some problems and methods of protection of the atmosphere.
Since 1980, Dr. Gajewski has been with the Institute of Heat Engineering and Fluid Mechanics of the Technical University of Wrocław – now Wrocław University of Technology. He worked as a researcher in powder technology, pneumatic transport, static electricity in two-phase gas-solid pipe flows, electrostatic hazards, and measurements. He developed a non-intrusive electrostatic method for measuring electrical and mechanical quantities in pneumatic transport and laid down dynamic safety criteria for fire and explosion hazard assessment. His current interests focus on tribocharging in rotating shaft-oil-lip seal systems and its effect on the braking torque of rotating shafts in machines having rotating parts, the electrochemistry of interface processes and changes in electrical double layers under dynamic conditions.
Juliusz B. Gajewski holds the position of Senior Lecturer – Reader in electrical engineering from 2001. He delivers lectures on electrical engineering and holds tutorials and classes with students.
Dr. Gajewski is a member of some national and international organizations including the European Working Party „Static Electricity in Industry” of the European Federation of Chemical Engineering. He also sits on editorial boards of three scientific journals including the Journal of Electrostatics. He organized or chaired the Scientific and the Organizing Committees of numerous international and national conferences.
Among his many interests and hobbies are: literature, photography, music, playing the clarinet, hiking in the mountains, high-mountain and alpine skiing, ski touring, swimming, canoeing, and bicycling.
The monograph is an overview of the development of a non-intrusive electrostatic method within last 50 years including the author’s own contribution to the method’s improvement, development, and application to measurements of the electric charge, mass flow rate, solids loading, and mean velocity of solid particles in pipes of pneumatic transport and in the air. Juliusz B. Gajewski analysed and published his own results of the almost 30-year research upon this measurement method in many various journals.
The first known attempt at inventing and developing the method was made about 50 years ago. It is based on the phenomenon of electrostatic induction which permits non-invasive measurements of the above flow quantities in the two-phase gas-solid flows. The probes, sensors, or transducers built on the basis of the method are non-contact ones and do not disturb the two-phase flow itself and its parameters to be measured. The mathematical models and various applications of the method presented by different authors and Dr. Gajewski as well as the original author’s static characteristics, amplitude-frequency characteristics and metrological analyses of some real measuring systems based on the method are presented in this book.
The monograph is intended for those who are interested in the modern non-intrusive metrology of electrical and non-electrical quantities with electrical and especially electrostatic methods based on electrostatic induction. It can provide a valuable source of information for engineers and scientific workers who would like to become acquainted with the method in itself, its physical and metrological basis and properties, and evolution within last 50 years.
