Screw Compressors: Mathematical Modelling and Performance Calculation
ISBN: 9783540242758 / Angielski / Twarda / 2005 / 152 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Althoughtheprinciplesofoperationofhelicalscrewmachines, ascompressors or expanders, have been well known for more than 100 years, it is only during the past 30 years that these machines have become widely used. The main reasons for the long period before they were adopted were their relatively poor e?ciency and the high cost of manufacturing their rotors. Two main developments led to a solution to these di?culties. The ?rst of these was the introduction of the asymmetric rotor pro?le in 1973. This reduced the bl- hole area, which was the main source of internal leakage by approximately 90%,...

Kinder Mit Migrationshintergrund: Zur Medialisierung Eines Bildungsproblems
ISBN: 9783658171728 / Niemiecki / Miękka / 2017 / 317 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Patricia Stosic untersucht in dieser qualitativ ausgerichteten Studie die Medialisierung wissenschaftlichen Wissens. Uber einen Zeitraum von zwolf Jahren rekonstruiert sie, wie und ob mediale Kommunikation (erziehungs-)wissenschaftliches Wissen in Anspruch nimmt, um das Thema des ungleichen Bildungserfolges zwischen Kindern mit und ohne Migrationshintergrund zu prozessieren. Im Anschluss an die Wissensverwendungsforschung und an Uberlegungen aus dem Bereich der Medien- und Kommunikationswissenschaften bezieht sich die Autorin dazu theoretisch auf die Systemtheorie Niklas Luhmanns. So...

Screw Compressors: Three Dimensional Computational Fluid Dynamics and Solid Fluid Interaction
ISBN: 9783642071645 / Angielski / Miękka / 2010 / 158 str. Termin realizacji zamówienia: ok. 20 dni roboczych. This book presents the most up-to-date methods of three-dimensional modeling of the fluid dymanics and the solid-fluid interaction within these machines, which are still being developed. Adding modeling to the design process makes it possible not only to predict flow patterns more accurately, and also to determine distorting effects on rotors and casing of pressure and temperature distribution within the compressor. Examples outline the scope of the applied mathematical model. This book presents the most up-to-date methods of three-dimensional modeling of the fluid dymanics and the solid-fluid interaction within these mac... |

Power Recovery from Low Grade Heat by Means of Screw Expanders
ISBN: 9781782421894 / Angielski / Twarda / 2014 / 272 str. Termin realizacji zamówienia: ok. 18-20 dni roboczych. Current concerns with climate change have resulted in greatly increased interest in power recovery from low grade heat sources. This includes both hot fluid streams which can be expanded directly to produce mechanical power and those which act as a source of heat to closed cycle power generation systems. Power recovery from low grate heat by means of screw expanders with a generalised overview of how best to recover power from such sources, based on thermodynamic considerations, which differs to the approach used in classical thermodynamics textbooks and which includes an...

Les connecteurs temporels du français
ISBN: 9789042018891 / Francuski / Miękka / 2006 / 137 str. Termin realizacji zamówienia: ok. 22 dni roboczych. Ce volume reunit six etudes sur les connecteurs temporels du francais, qui ont ete presentees lors de la journee d'etudes Grammatica organisee a l'Universite d'Artois le 25 mai 2005 par Estelle Moline et Dejan Stosic. Il commence par une etude diachronique de Bernard Combettes, qui aborde le probleme de l'alternance que / ce que dans la constitution des locutions conjonctives temporelles en ancien francais, en analysant en detail le cas de des (ce) que. Ensuite, Walter De Mulder etudie l'adverbe maintenant a la fois dans ses emplois temporels et non temporels et se propose de montrer que cet...
