  • Explosives and propellants contain considerable chemical energy that can be converted into rapid expansion. In contrast to the simple burning of a fuel, explosives and propellants are self-contained and do not need an external supply of oxygen via air. Since their energy content inherently creates the risk of accidental triggering of the explosive reaction, the correct synthesis, formulation, and handling during production and use are of utmost importance for safety, necessitating specialist knowledge on energetic materials, their characteristics, handling and applications.

  • 1. Background of the Development The shape of gears is very attractive to the PM manufacturing process. Spur gears as well as helical gears can be shaped by compaction. The performance of gears is influenced beneath the geometrical design mainly by the material parameters tooth root strength σFE and pitting resistance σHlim. The comparison of these values from PM gears to wrought steel gears shows clearly, that PM gears can only be used in low loaded applications (Fig. 1).

  • The U.S. economic expansion is now in its tenth year, showing no signs of slowing down. The rate of labor productivity growth has doubled in recent years, instead of falling as the expansion matured as in previous postwar expansions. Moreover, core inflation remains low despite record employment and the lowest jobless rates in a generation. Our sustained economic strength with low inflation suggests that the U.S.

  • Internal combustion engines have experienced an enjoyed monopoly for almost a century as power sources of road transport vehicles. But, in the same period, vehicle ownership and mileages increased to a level that the resulting petroleum based fuel consumption, urban air pollutants and green house gas emissions (the challenging triad) have became great concern especially for past a few decades.

  • Fuel Injection is a key process characterising the combustion development within Spark- Ignition (SI) and Compression Ignition (CI) Internal Combustion Engines (ICEs). Fuel Injection and Spray Behaviour in fact largely control the fuel-air mixing, combustion process efficiency, stability, the production of noxious species, the radiated noise, etc.The proper design of the fuel injection system requires the employment of both experimental and numerical techniques, sometimes coupled for optimisation procedures....

  • The contributions in this book present an overview of utting edge research on natural gas which is a vital component of world’s supply of energy. Natural gas is combustible mixture of hydrocarbon gases, primarily methane but also heavier gaseous hydrocarbons such as ethane, propane and butane. Unlike other fossil fuels, natural gas is clean burning and emits lower levels of potentially harmful by-products into the air. Therefore, it is considered as one of the cleanest, safest, and most useful of all energy sources applied in variety of residential, commercial and industrial fields....

  • Urban transport system is crucial for economic and social development of our society as it meets challenging mobility requirements of urban agglomerations. The requirements are challenging because road transport, which is the most problematic transport mode, is dominating the urban transport activities. The main problems with the road transport are that the infrastructure is not generally suffi cient for whole traffi c conditions and the vehicles are powered by internal combustion engines that require fossil fuels to burn and emit pollutant emissions during their normal operations....

  • In addition to the aforementioned direct benefits of using alternative fuels for cement manufacturing, there are numerous life-cycle benefits and avoided costs that are realized. Alternative fuels are essentially the waste products of other industrial or agricultural processes, and due to their sheer volume and potentially their toxicity, they pose a major solid waste management challenge in many countries.

  • The energy demand for the endothermic gasification reaction is met by the combustion of residual char in the fast bed combustor. The circulating bed materials act as heat carrier between the two fluidized beds and maintain the required temperature in gasifier. Therefore, the hydrodynamics of such a dual fluidized beds system needs to be thoroughly understood for successful design and operation of the system for industrial application.
