To counter global warming and ozone layer depletion, in recent times a lot of alternative refrigeration methods have been proposed. Elastocaloric effect, a solid state cooling technology, is one of the most recent and potential ones to phase-out traditional vapor compression cooling systems. In this work, an elastocaloric system based on superelastic Nickel-Titanium has been proposed. A proven mathematical material model has been used to predict various design parameters for such a system. The heat transfer characteristics of the model have been modified to accommodate the use of water as the heat transfer fluid. The effect of strain rate on achieving the elastocaloric effect is also been explored. Finally, performance parameters of the system are calculated and compared to the conventional systems.

Download Shape Memory Alloy Actuators Book in PDF, ePub and Kindle
This book provides a systematic approach to realizing NiTi shape memory alloy actuation, and is aimed at science and engineering students who would like to develop a better understanding of the behaviors of SMAs, and learn to design, simulate, control, and fabricate these actuators in a systematic approach. Several innovative biomedical applications of SMAs are discussed. These include orthopedic, rehabilitation, assistive, cardiovascular, and surgery devices and tools. To this end unique actuation mechanisms are discussed. These include antagonistic bi-stable shape memory-superelastic actuation, shape memory spring actuation, and multi axial tension-torsion actuation. These actuation mechanisms open new possibilities for creating adaptive structures and biomedical devices by using SMAs.

Download S M a Shape Memory Alloy Cooling System by Peltier Cells Book in PDF, ePub and Kindle
Shape Memory Alloys (S.M.A.), due to their interesting and promising features in terms of transmittable forces and deformations, are well doing for themselves for several engineering applications: from aeronautics to civil field, from surgery to electronics and so on. Among the others, the morphing wing field is benefiting of S.M.A.: some airfoil geometrical features (f.i. camber, chord) and some wing characteristics (twist angle, swept, winglets) are, at the moment, object of investigations aiming at producing suitable, remarkable geometry variations thus achieving optimal configurations for different flight regimes. A considerable incentive towards this direction has been given by the advent of above mentioned smart materials, generally guaranteeing compactness, cost and weight reduction, high integration level. Among the others, a morphing application focusing on flap zone chamber control, based on S.M.A. ribbon integrated within the structure, has been carried out and a lab technology demonstrator has been built and tested. However, the intrinsic limit of S.M.A., that is the necessity of a heating and cooling for activation and deactivation, penalized the frequency work range.

Download Advanced Elastocaloric Cooling Devices Based on Shape Memory Alloy Films Book in PDF, ePub and Kindle
Elastocaloric cooling is an emerging solid-state cooling technology with the potential to provide environmentally friendly, efficient cooling. The elastocaloric effect in superelastic shape memory alloy films is used to develop advanced cooling devices for small-scale applications. Cascaded and parallelized devices are developed to increase device temperature span and cooling capacity. The concepts are proven experimentally, a maximum temperature span of 27° C is achieved in a cascaded device.

Download Engineering Aspects of Shape Memory Alloys Book in PDF, ePub and Kindle
Engineering Aspects of Shape Memory Alloys provides an understanding of shape memory by defining terms, properties, and applications. It includes tutorials, overviews, and specific design examples—all written with the intention of minimizing the science and maximizing the engineering aspects. Although the individual chapters have been written by many different authors, each one of the best in their fields, the overall tone and intent of the book is not that of a proceedings, but that of a textbook. The book consists of five parts. Part I deals with the mechanism of shape memory and the alloys that exhibit the effect. It also defines many essential terms that will be used in later parts. Part II deals primarily with constrained recovery, but to some extent with free recovery. There is an introductory paper which defines terms and principles, then several specific examples of products based on constrained recovery. Both Parts III and IV deal with actuators. Part III introduces engineering principles while Part IV presents several of the specific examples. Finally, Part V deals with superelasticity, with an introductory paper and then several specific examples of product engineering.

Download Shape Memory Alloy Engineering Book in PDF, ePub and Kindle
Shape Memory Alloy Engineering introduces materials, mechanical, and aerospace engineers to shape memory alloys (SMAs), providing a unique perspective that combines fundamental theory with new approaches to design and modeling of actual SMAs as compact and inexpensive actuators for use in aerospace and other applications. With this book readers will gain an understanding of the intrinsic properties of SMAs and their characteristic state diagrams, allowing them to design innovative compact actuation systems for applications from aerospace and aeronautics to ships, cars, and trucks. The book realistically discusses both the potential of these fascinating materials as well as their limitations in everyday life, and how to overcome some of those limitations in order to achieve proper design of useful SMA mechanisms. Discusses material characterization processes and results for a number of newer SMAs Incorporates numerical (FE) simulation and integration procedures into commercial codes (Msc/Nastran, Abaqus, and others) Provides detailed examples on design procedures and optimization of SMA-based actuation systems for real cases, from specs to verification lab tests on physical demonstrators One of the few SMA books to include design and set-up of demonstrator characterization tests and correlation with numerical models
