Sommario/riassunto |
|
Bridging the gap between the well-known technological description of gasification and the underlying theoretical understanding, this book covers the latest numerical and semi-empirical models describing interphase phenomena in high-temperature conversion processes. Consequently, it focuses on the description of gas-particle reaction systems by state-of-the-art computational models in an integrated, unified form. Special attention is paid to understanding and modeling the interaction between individual coal particles and a surrounding hot gas, including heterogeneous and homogeneous chemical re |

institution and provide a comprehensive view of the United Nations Compensation Commission and its work in the aftermath of the Gulf War. In this volume, the first of two on the UNCC's work, the authors explain that the United Nations Security Council established the ad hoc compensation commission to address reparations as a component of the ceasefire following Iraq's 1990-91 invasion and occupation of Kuwa |
