Hardcover. Condition: Good. THERE ARE NO TARIFFS OR CUSTOMS DUTIES ON BOOKS. German text. The Chymical Wedding of Christian Rosenkreutz is one of the most important writings of esoteric Christianity, first published anonymously in German in 1616. It is an allegorical story divided into seven journeys about how Christian Rosenkreutz was invited to a castle to assist the 'chymical wedding' of the king and queen. 'Chymical' is an old form of the word chemical and refers to alchemy, whose aim is the uniting of opposites -- hence, the sacred wedding. In this edition there are notes by Rudolf Steiner. Decorated blue boards and spine have only light wear and are strong. Dedication on first page and owner's name on front endpaper. One small underlining noticed. No other annotations. Text clean and bright, just a few marks occasionally.Sturdy and attractive volume of this important work.

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Better understanding of combustion near walls has a significant interest in lean combustion using large excess of air, for example in the internal combustion engine concept Homogeneous Charge Combustion Ignition (HCCI). In this work numerical simulations have been conducted to study different aspects of wall effects in the combustion of lean, premixed, hydrogen and methane fuel/air mixtures. The simulations have been performed with the program CRESLAF, a part of the CHEMKIN software. The wall effects must be analyzed with respect to the complicated nature of the combustion process. I the near wall boundary layer, transport of momentum, heat and mass are done in a manner that may affect the hundreds of elementary chemical reaction steps. In addition, the wall may be chemically active and lead to termination of radical chains, or through catalytic reactions that may emit products from the wall and retard the homogeneous reactions. The results presented in this work may be used by designers of combustors and microchannel reactors,where calculations cannot give accurate results unless the effects of the walls are accounted for.
