Описание: This book is devoted to studies of unsteady heat and mass exchange processes taking into account thermochemical destruction of thermal protective materials, research of transpiration cooling systems, thermal protection of composite materials exposed to low-energy disturbances, as well as the numerical solution of heat and mass transfer of the exchange. It proposes several mathematical models of passive and active thermal protection systems with regard to factors such as surface ablation, surface roughness, phase transition of a liquid in porous materials, rotation of the body around its longitudinal axis, and exposure to low-energy disturbances. The author studies the possibilities to control thermochemical destruction and heat mass exchange processes in transpiration cooling systems exposed to low-energy disturbances. The numerical analysis of the heat and mass exchange process in carbon plastics under repeated impulse action is also presented. The numerical solutions of problems are compared with the known experimental data. The book is intended for specialists in the field of thermal protection and heat mass exchange, as well as graduate and undergraduates in physics and mathematics.
Описание: Tbe main purpose of this work was to find a way of placing a meaningful scientific payload within the upper atmosphere of Mars such that certain scientific measurements become possible. So the altitude range covered and the possible dweIl time are relevant design drivers and will be explored in greater detail within this thesis. Either concept of flying on Mars, however, be it heavier or lighter than air (read: heavier or lighter than carbon dioxide) is restricted to altitodes weil below 10 km. Since any sustained light at that altitode or higher in such a thin atmosphere is teehnically impractical, so is ascending to that altitode with - sounding rocket. Therefore - team of scientists from several research institutes around Europe fonned a scientific committec. Together with engineers and scientists from tbe Mars Society Germany and tbe University ofthe Federal Armed Forces of Germany in Munich (UBW) the committee drafted a reference scientific mission scenario 1] to: find ways to da exactly that: providing an instrument suite with access to a large altitu. de range and. meaningful dwell time (see 10. 3. 1 starting onp. ge 208). Tbc most practical approach was found in an inflatable entry vehicle that can provide the largest and lightest possible configuration. Since 00 such attempts have yet been m. ade, the work described herein focuses mostly on the mathematical thcory and the technical peculiarities of such a system, but also treats mission design and testing aspects. 1.
Описание: In this book selected aerothermodynamic design problems in hypersonic vehicles are treated. Where applicable, it emphasizes the fact that outer surfaces of hypersonic vehicles primarily are radiation-cooled, an interdisciplinary topic with many implications.
Описание: This is a history of the US military`s `Dyna-Soar` project to build a hypersonic reusable `space plane`, which lasted from 1945 to 1963.

Описание: This new edition includes brand-new developments in the modeling of processes in the column apparatuses. It analyzes the radial velocity component and axial variation in the axial velocity in the column. These models are described in five new chapters. The book presents models of chemical and interphase mass transfer processes in industrial column apparatuses, using convection-diffusion and average-concentration models. It also introduces average concentration models for quantitative analysis, which use the average values of the velocity and concentration over the cross-sectional area of the column. The new models are used to analyze a broad range of processes (simple and complex chemical reactions, physical and chemical absorption, physical and chemical adsorption, catalytic reactions in the cases of physical and chemical adsorption mechanism), and make it possible to model sulfur dioxide gas purification processes.
Описание: This book is written to help and enable students in how to observe biological specimens in terms of viscosity, mass, elasticity and work producing elements. The observations are related to underlying chemical reactions by means of strain (fractional length change) sensitivity of the reactions, and a theory is developed how to connect these. Their mathematical derivation is complex when three or more states are involved, but a method is presented here to demonstrate how to simplify this complex problem. Basic mathematical solutions that are useful for this book, are presented (Fourier and Laplace transforms, differential equations, matrix operations) together with Fortran programs in the Appendix.

Описание: This book investigates how broadband internet can be provided to remote and isolated communities through the use of satellite and other enabling technologies, in the form of a self-contained broadband apparatus. It discusses how the proposed design can help bridge the digital divide by removing one of the main hurdles to adopting technologies: infrastructure. In turn, the book explores how the lack of infrastructure, especially with regard to connectivity and electricity, can be addressed by exploiting new technological advances in a number of fields, notably the newly proposed large broadband satellite constellations. In closing, it uses concrete examples to demonstrate the potential positive impacts of a “broadband ecosystem” on economics, governance and society, and on achieving the United Nations’ Sustainable Development Goals.
