This open access book presents the findings of Collaborative
Research Center Transregio 40 (TRR40), initiated in July 2008 and
funded by the German Research Foundation (DFG). Gathering
innovative design concepts for thrust chambers and nozzles, as well
as cutting-edge methods of aft-body flow control and
propulsion-component cooling, it brings together fundamental
research undertaken at universities, testing carried out at the
German Aerospace Center (DLR) and industrial developments from the
ArianeGroup. With a particular focus on heat transfer analyses and
novel cooling concepts for thermally highly loaded structures, the
book highlights the aft-body flow of the space transportation
system and its interaction with the nozzle flow, which are
especially critical during the early phase of atmospheric ascent.
Moreover, it describes virtual demonstrators for combustion
chambers and nozzles, and discusses their industrial applicability.
As such, it is a timely resource for researchers, graduate students
and practitioners.
This book provides a selection of contributions to the DIPSI
workshop 2019 (Droplet Impact Phenomena & Spray Investigations)
as well as recent progress of the Int. Research Training Group
"DROPIT".The DIPSI workshop, which is now at its thirteenth
edition, represents an important opportunity to share recent
knowledge on droplets and sprays in a variety of research fields
and industrial applications. The research training group "DROPIT"
is focused on droplet interaction technologies where microscopic
effects influence strongly macroscopic behavior. This requires the
inclusion of interface kinetics and/or a detailed analysis of
surface microstructures. Normally, complicated technical processes
cover the underlying basic mechanisms, and therefore, progress in
the overall process modelling can hardly be gained. Therefore,
DROPIT focuses on the underlying basic processes. This is done by
investigating different spatial and/or temporal scales of the
problems and by linking them through a multi-scale approach. In
addition, multi-physics are required to understand e.g. problems
for droplet-wall interactions, where porous structures are
involved.

This monograph provides the fundamentals of dimensional analysis
and illustrates the method by numerous examples for a wide spectrum
of applications in engineering. The book covers thoroughly the
fundamental definitions and the Buckingham theorem, as well as the
choice of the system of basic units. The authors also include a
presentation of model theory and similarity solutions. The target
audience primarily comprises researchers and practitioners but the
book may also be suitable as a textbook at university level.
This book describes useful analytical methods by applying
them to real-world problems rather than solving the usual
over-simplified classroom problems. The book demonstrates the
applicability of analytical methods even for complex problems and
guides the reader to a more intuitive understanding of approaches
and solutions. Although the solution of Partial Differential
Equations by numerical methods is the standard practice in
industries, analytical methods are still important for the critical
assessment of results derived from advanced computer simulations
and the improvement of the underlying numerical techniques.
Literature devoted to analytical methods, however, often focuses on
theoretical and mathematical aspects and is therefore useless to
most engineers. Analytical Methods for Heat Transfer and Fluid Flow
Problems addresses engineers and engineering students. The second
edition has been updated, the chapters on non-linear problems and
on axial heat conduction problems were extended. And worked out
examples were included.

Einleitung.- Grundlagen.- Hauptsatze der Thermodynamik.- Stoffe und
deren thermodynamische Beschreibung.- Anwendungen der Hauptsatze.-
Maximale Arbeit und Energie.- Technische Anwendungen.
Die Aufgabensammlung zum Lehrbuch "Thermodynamik kompakt" fasst die
wichtigsten Formeln zur Thermodynamik zusammen. Sie erganzt in
hervorragender Weise das Lehrbuch derselben Autoren. Der Aufbau
orientiert sich an der Gliederung des Lehrbuchs und enthalt
Aufgaben und durchgerechnete Loesungen u.a. zu diesen Themen:
Hauptsatze der Thermodynamik und deren Anwendung Stoffe und deren
Beschreibung Maximale Arbeit und Exergie Technische Anwendungen,
wie z.B. Kreisprozesse, Stroemungsprozesse, feuchte Luft und
Chemische Reaktionen. Die einzelnen Aufgaben zu den Kapiteln werden
erganzt durch vollstandige Prufungen im Anhang des Buches. Die
Loesungen hierzu koennen aus dem Internet heruntergeladen werden.
Die Darstellungen der ersten Auflage haben sich bewahrt. Fur die
zweite Auflage wurden in mehreren Kapiteln weitere Rechenaufgaben
hinzugefugt und es wurde eine weitere Klausur im Anhang erganzt.
Bei verschiedenen Aufgaben wurden die Loesungen prazisiert und
verschiedene Schreibfehler im Text korrigiert.
