Electrorheological Fluids And Magnetorheological Suspensions

This book contains up-to-date information on the state of the art of research and applications in electro- and magnetorheology. A total of 130 papers are presented in four sections. The first section is devoted to the various applications of ER and MR fluids, like polishing, microfluidics, vibration control, robots, shock absorbers and dampers, MR and ER valves. The second part deals with the experimental characterization as well as the theoretical prediction of the mesostructure resulting from field-induced phase separation. The dynamics of phase separation is also included in this section. The third section is about the material properties; it includes papers on new compositions of ER or MR fluids, polymer blends, magneto- or electroactive elastomers and gels. The last section, about physical mechanisms, presents experiments and theories on the rheology of the fluids and its connection with microhydrodynamics and the structure of field-induced aggregates.

This unique volume presents the scientific progress, state-of-art technology, and thrust areas to be focused in electrorheology (ER) and magentorheology (MR). In the last couple of years, this area produced significant impacts on automobile industry, bridge and building construction, aerospace industry, and defense industry. Recent innovation in this area lead to new technology, which has great impact on energy production and energy conservation. This book includes all papers presented at the 12th International Conference on ER Fluids and MR Suspensions, held in Philadelphia, USA, August 16 to 20, 2010, providing a comprehensive overview of this flourishing area. It is an essential source of reference for chemists, engineers, physicists, and materials scientists. It is also suitable for science and engineering students.

The theme of the above conference was the SYNERGY generated by the interaction of the different disciplines relevant to ERF and MRS investigations. To stimulate this theme, all lecture sessions included a mixture of papers — one session contained applications, methodology, particle dynamics, structure characteristics and whatever is germane to the objective of furthering the standing of the subject. ‘Lead-in’ lectures were given by experts who had not recently been able to explain their work to colleagues in their own discipline. They were also charged with justifying the relevance of their area of work to the ESF/MRS field as a whole.

This volume covers the most recent progress of research work on electrorheological (ER) and magnetorheological (MR) industrial applications related to controllable damping, ER/MR fundamental mechanisms, and understanding the potential of new classes of field responsive materials.

Electrorheological (ER) fluids and magnetorheological (MR) suspensions show dramatic and reversible rheological changes when the electric or magnetic field is applied. Over the past several years, their performance and reliability have been significantly improved and their potential applications and acceptances have been widened. These fluids may make a tremendous impact on industry and technology.This volume contains a total of 107 papers which are most up to date and which give probably the best information on the state of the art of the ERF/MRS field. It covers the fields of material technology, mechanisms, bridging structure and properties on ER fluids, MR suspensions and ferrofluids, and the fields of their applications, i.e. damping devices, clutches, braking devices, actuators, optical devices, polishing devices and so on.

ERMR 2006 included invited speakers, technical presentations, poster presentations, and a student paper competition. At the conference banquet, Dr. David Carlson of Lord Corporation addressed the conference attendees and gave a stirring speech on the history of ER and MR fluids, as well as current and future applications. A unique feature of the ERMR Conferences is that they comprehensively cover issues ranging from physics to chemistry to engineering applications of ER and MR materials held in a general session to enhance the interaction between the scientists and engineers. The sessions in ERMR 2006 were organized based into two Symposia: a) Materials and b) Applications. Topics covered in the Materials Symposium included: mechanisms, preparation, and characterization of ER and MR materials. Topics covered in the Applications Symposium included: ER and MR devices, control systems, system integration, and applications. This structure was implemented in order to enable interaction between attending scientists and engineers in both the Materials Symposium and the Applications Symposium, and to enhance the free flow of ideas, and the potential collaborative research opportunities.
