Les machines mouvement alternatif ont t invent es au XIe si cle par El-Cezeri. Depuis lors, plusieurs modifications leur ont t apport es. Aujourd'hui, nous disposons de moteurs plus efficaces, plus durables et plus respectueux de l'environnement, mais cela ne suffit pas. Dans ce livre, la technologie HCCI a t tudi e de mani re approfondie en tant que nouvelle technique pour les moteurs diesel en termes de performances de combustion et d' missions de gaz d' chappement.

As m quinas de movimento alternativo foram inventadas no s culo XI por El-Cezeri. Desde essa altura at hoje, foram-lhes aplicadas v rias modifica es. Atualmente, dispomos de motores mais eficientes, mais duradouros e mais amigos do ambiente, mas isso n o suficiente. Neste livro, a tecnologia HCCI foi abordada de forma abrangente como uma nova t cnica em motores a gas leo em termos de desempenho de combust o e emiss es de escape.

Le macchine a ricircolo sono state inventate nell'XI secolo da El-Cezeri. Da allora ad oggi, sono state apportate diverse modifiche. Oggi disponiamo di motori pi efficienti, pi duraturi e pi rispettosi dell'ambiente, ma non sufficiente. In questo libro, la tecnologia HCCI stata trattata in modo esaustivo come una nuova tecnica nei motori diesel in termini di prestazioni di combustione e di emissioni di scarico.

Hubkolbenmaschinen wurden im 11. Jahrhundert von El-Cezeri erfunden. Von diesem Tag an wurden sie mehrfach modifiziert. Heute verf gen wir ber effizientere, langlebigere und umweltfreundlichere Motoren, aber das ist nicht genug. In diesem Buch wird die HCCI-Technologie als neue Technik bei Dieselmotoren im Hinblick auf Verbrennungsleistung und Abgasemissionen umfassend behandelt.

In this book, the authors mentioned the computational fluid dynamics (CFD) applications for mining engineering. Firstly, the ANSYS program is briefly explained and the literature is examined. Rock mechanics is an essential subject for mining engineering. It is modeled to inform the material properties. A tough stone was given for example. The mine ventilation is done correctly to prevent explosions. Therefore, the fan blade design and fan performance are modeled. The methane and air mixture (two-phase) behavior is also simulated in an underground coal mine. Dust modeling is done to prevent dust explosions in underground mines. Finally, the sealing material as concrete is modeled in underground mines.
