Opis

Thermal vibrational convection is concerned with, firstly, the study of vibrational effects on the transfer of heat and mass and secondly, with the study of fluid behaviour under the effect of vibration. This field has applications in hydrodynamics and, increasingly, in the study of heat and mass transfer in microgravity and weightlessness. The mathematical principles and ideas that underline all these and more traditional areas of fluid dynamics are presented here.

Recent increasing awareness of the ways in which vibrational effects can affect low–gravity experiments have renewed interest in the study of thermal vibrational convection across a wide range of fields. For example, in applications where vibrational effects are used to provide active control of heat and mass transfer, such as in heat exchangers, stirrers, mineral separators and crystal growth, a sound understanding of the fundamental theory is required. In Thermal Vibrational Convection, the authors present the theory of vibrational effects caused by a static gravity field, and of fluid flows which appear under vibration in fluid–filled cavities. The first part of the book discusses fluid–filled cavities where the fluid motion only appears in the presence of temperature non–uniformities, while the second considers those situations where the vibrational effects are caused by a non–uniform field. Throughout, the authors concentrate on consideration of high frequency vibrations, where averaging methods can be successfully applied in the study of the phenomena. Written by two of the pioneers in this field, Thermal Vibrational Convection will be of great interest to scientists and engineers working in the many areas that are concerned with vibration, and its effect on heat and mass transfer. These include hydrodynamics, hydro–mechanics, low gravity physics and mechanics, and geophysics. The rigorous approach adopted in presenting the theory of this fascinating and highly topical area will facilitate a greater understanding of the phenomena involved, and will lead to the development of more and better–designed experiments.
