This book aims to develop systematic design methodologies to model-based nonlinear control of aeroengines, focusing on (1) modelling of aeroengine systems-both component-level and identification-based models will be extensively studied and compared; and (2) advanced nonlinear control designs-set-point control, transient control and limit-protection control approaches will all be investigated. The model-based design has been one of the pivotal technologies to advanced control and health management of propulsion systems. It can fulfil advanced designs such as fault-tolerant control, engine modes control and direct thrust control. As a consequence, model-based design has become an important research area in the field of aeroengines due to its theoretical interests and engineering significance. One of the central issues in model-based controls is the tackling of nonlinearities. There are publications concerning with either nonlinear modelling or nonlinear controls; yet, they are scattered throughout the literature. It is time to provide a comprehensive summary of model-based nonlinear controls. Consequently, a series of important results are obtained and a systematic design methodology is developed which provides consistently enhanced performance over a large flight/operational envelope, and it is thus expected to provide useful guidance to practical engineering in aeroengine industry and research.

The tubular thermosyphon is a very simple idea for transferring heat. Fluid inside a tube is circulated by buoyancy forces and thus carries thermal energy from the hot end to the cold end with great efficiency. The device has many uses, from cooling equipment and machinery to recovering waste heat recovery and conserving energy. However the actual operating details of the thermosyphon are more complex and change dramatically with the circumstances. The length and diameter of the tube, the nature and state of the fluid, the strength and variation of the body force field all influence the internal circulation pattern and thus create different operating characteristics. This book deals with each of these variations thoroughly and systematically. Emphasis is placed on the physical principles underlying thermal behavior under single-phase or evaporative conditions, whether the tube is stationary or rotating and whether it is straight or bent. Consideration is also given to other devices having a similar purpose. This study will be of special interest to mechanical, chemical, electrical and geotechnical engineers, and graduate students concerned with thermosyphon technology.
