"This book gathers the proceedings of the 11th workshop on Direct and Large Eddy Simulation (DLES), which was held in Pisa, Italy in May 2017. The event focused on modern techniques for simulating turbulent flows based on the partial or full resolution of the instantaneous turbulent flow structures, as Direct Numerical Simulation (DNS), Large-Eddy Simulation (LES) or hybrid models based on a combination of LES and RANS approaches. In light of the growing capacities of modern computers, these approaches have been gaining more and more interest over the years and will undoubtedly be developed and applied further. The workshop offered a unique opportunity to establish a state-of-the-art of DNS, LES and related techniques for the computation and modeling of turbulent and transitional flows and to discuss about recent advances and applications."

"This is a book about thermodynamics, not history, but it adopts a semi-historical approach in order to highlight different approaches to entropy. The book does not follow a rigid temporal order of events, nor it is meant to be comprehensive. It includes solved examples for a solid understanding. The division into chapters under the names of key players in the development of the field is not intended to separate these individual contributions entirely, but to highlight their different approaches to entropy. This structure helps to provide a different view-point from other text-books on entropy."

"This SpringerBrief presents a recent advancement in modeling and measurement of the effect of surface wettability on the defrost process. Carefully controlled laboratory measurements of the defrosting of cooled surfaces are used to reveal the effect of surface wetting properties on the extent and speed of frost removal by melting or slumping. The experiments are accompanied by visualization of frost removal at several defrosting conditions. Analysis breaks the defrost process into three stages according to the behavior of the meltwater. Surface wetting factors are included, and become significant when sufficient meltwater accumulates between the saturated frost layer and the surface. The book is aimed at researchers, practicing engineers and graduate students."

"Thermodynamics is a subject that all engineering students have to face and that most of them treat with great respect. This makes it all the more important to offer a good and easy-to-understand approach to the laws of energy conversion. This is what this textbook is intended to do: It covers the basics of classical technical thermodynamics as they are typically taught at universities: The first and second law of thermodynamics as well as equations of state are explained for idealized and real fluids which are subject to a phase change. Thermodynamic mixtures, e.g. humid air, are treated as well as chemical reactions. Components and thermodynamic cycle that convert energy are presented. The book attaches great importance to drawings and illustrations, which should make it easier to comprehend complex matter. Technical applications and apparatus are presented and explained. Numerous exercises and examples conclude the book and contribute to a better understanding of the theory."

"This authoritative reference presents a comprehensive review of the evolution of plasma science and technology fundamentals over the past five decades. One of this field’s principal challenges has been its multidisciplinary nature requiring coverage of fundamental plasma physics in plasma generation, transport phenomena under high-temperature conditions, involving momentum, heat and mass transfer, and high-temperature reaction kinetics, as well as fundamentals of material science under extreme conditions. The book is structured in five distinct parts, which are presented in a reader-friendly format allowing for detailed coverage of the science base and engineering aspects of the technology including plasma generation, mathematical modeling, diagnostics, and industrial applications of thermal plasma technology. This book is an essential resource for practicing engineers, research scientists, and graduate students working in the field."

"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."

"Koiom Huidisasi fasa jamak gas-cair-padat (G-GP) mempakan suatu alat yang berfungsi sebagai alat kontak antara fasa gas, cair dan padat yang telah banyak dikembangkan dan digunakan dalam teknologi proses. Penggunaan unggun partikel halus akan menghasilkan sistem yang Iebih homogen, Iuas kontak perpindahan massa dan panas lebih besar serta pengadukan yang Iebih sempuma.
Metode yang digunakan untuk menentukan koetisien perpindahan massa pada kolom fluidisasi fasa jamak adalah dengan mendata proiil konsentrasi cairan terhadap ketinggian kolom, dan kemudlan diselesalkan dengan menggunakan suatu model matematika yaitu Model Dispersi Aksiai. Hasil ini selaniutnya akan dibandingkan dengan perhitungan menggunakan Continuous Stined Tank ReactorModeI.
Makalah ini membahas hasil penelitian daiam menentukan koetisien perpindahan massa pada kolom Huidisasi fasa jamak berpariikel halus serta mengamati pengaruh kecepatan Huida baik gas maupun cair serta diameter partikei unggun terhadap koefisien perpindahan massa."

"Menurut studi dari WHO pada tahun 2012, Indonesia berada pada peringkat ke 5 dengan jumlah bayi prematur terbanyak di dunia. Kebutuhan akan inkubator yang portabel dan murah semakin meningkat. Oleh karena itu, perlu dibuat inkubator portabel dengan harga yang terjangkau serta cocok untuk iklim tropis di Indonesia. Dengan menggunakan prinsip grashof dapat dibuat inkubator yang pemanasnya bersumber dari lampu pijar dan dengan menggunakan sensor thermostat, panas dari inkubator tersebut dapat diatur sesuai dengan kebutuhan. Performa dari inkubator dengan menggunakan prinsip grashof ini memiliki kebergantungan erat dengan keadaan temperatur ambien yang ada di sekitar inkubator. Pada simulasi inkubator bayi kembar dengan menggunakan aplikasi ANSYS CFX didapati bahwa inkubator mampu menaikkan suhu hingga 7°C untuk temperatur ambien 25°C, 28°C, dan 31°C. Aliran udara pada inkubator ini terbentuk akibat proses konveksi alamiah dimana udara yang memiliki temperatur lebih tinggi bergerak ke atas dan sebaliknya.

Based on 2012 study from WHO, Indonesia is ranked 5th with the most premature infant in the world. The need for a portable and affordable incubator keeps increasing. There’s a need to make portable incubator with affordable price and suitable for use in Indonesia tropical climate. By using grashof number principle we can make an incubator using lightbulb as the heat source where the temperature settings can be adjusted using thermostat sensor and controller. The performance of this type of incubator have a strong relationship with the amvient temperature outside the incubator. Based on the simulation on the twin baby incubator using ANSYS CFX app we can see that this incubator can raise the temperature inside the cabin up to 7°C for ambient temperature of 25°C, 28°C, dan 31°C. The fluid circulation in this incubator is created from natural convection law where fluid with a higher temperatur will circulate to the top and vice versa."
