Book Description
This Handbook provides researchers, faculty, design engineers in industrial R&D, and practicing engineers in the field concise treatments of advanced and more-recently established topics in thermal science and engineering, with an important emphasis on micro- and nanosystems, not covered in earlier references on applied thermal science, heat transfer or relevant aspects of mechanical/chemical engineering. Major sections address new developments in heat transfer, transport phenomena, single- and multiphase flows with energy transfer, thermal-bioengineering, thermal radiation, combined mode heat transfer, coupled heat and mass transfer, and energy systems. Energy transport at the macro-scale and micro/nano-scales is also included. The internationally recognized team of authors adopt a consistent and systematic approach and writing style, including ample cross reference among topics, offering readers a user-friendly knowledgebase greater than the sum of its parts, perfect for frequent consultation. The Handbook of Thermal Science and Engineering is ideal for academic and professional readers in the traditional and emerging areas of mechanical engineering, chemical engineering, aerospace engineering, bioengineering, electronics fabrication, energy, and manufacturing concerned with the influence thermal phenomena.

Book Description
This fully revised, industry-standard resource offers practical details on every aspect of the fundamentals necessary for understanding thermal spray technology, from powder all the way to the final part. The second edition is presented in a reader-friendly format that is split into four parts. Part I presents a review of thermal spray coating and its position in the broad field of surface modification technologies. Highlights of combustion and thermal plasmas are given with an expanded treatment of in-flight plasma-particle interactions. The second and third parts deal respectively with an updated presentation of thermal spray technologies and coating formation, including solution and suspension plasma spraying. The last part of the book includes a comparative analysis of different thermal spray processes, which is essential for the optimal selection of the appropriate thermal spray process in a given application. Coverage of system integration has been expanded with the addition of a detailed discussion of online instrumentation and process diagnostics and numerous examples of industrial scale spray booth designs. Attention is also given to coating finishing and health and safety issues. An extensive review is presented of thermal spray applications grouped in terms of process objectives and present use in different industrial sectors. This book will serve as an invaluable resource as a textbook for graduate courses in the field and as an exhaustive reference for professionals involved in the thermal spray field.

Book Description
Plasma Spraying is a coating process designed to deposit accelerated molten or semi-molten coating materials on prepared substrates. Suspension Plasma Spraying (SPS) is one type of Plasma Spraying with enhanced characteristics. Numerical modeling of this process helps us to find optimum operating parameters such as suspension injection position and standoff distance for substrates. A three-dimensional model of a plasma spraying system with radial suspension injection is studied in this work. To model turbulent flow of plasma, Reynolds Stress Model (RSM) is utilized. In addition, Lagrangian approach is used to track particles and two-way coupling is used to consider the effect of suspension on the gas flow. It should be mentioned that when mass flow rate of suspension is very high, the plasma plume cannot melt all particles that fly near the centerline. It is found that with optimum suspension mass flow rate, in general, almost all particles flying near the centerline are melted and reach high temperature. Furthermore, the effect of angle of suspension injection is studied. One can find that angles toward the gun give more penetration of suspension in the plasma plume, resulting in better melting and higher speed of particles. Finally, particle temperature, velocity and size distributions are studied at different standoff distances with respect to the plasma gun exit. It is shown that optimum standoff distance for the studied particles and plasma plume properties is between 3 to 6 cm. Less than 3 cm standoff distance, particles have no time to reach the melting point and the base liquid would not evaporate completely; and with more than 6 cm standoff distance, particles’ velocity will be significantly reduced. It should be mentioned that trajectory and penetration of suspension completely depends on velocity of suspension on one hand, and on the other hand temperature and velocity of the plasma plume. It is clear that for each condition, mass flow rate and velocity of plasma, the related modeling should be done to find velocity and temperature of particles.
