36. Lateral mixing of solids in bubbling fluidized beds – experimental quantification
Sammanfattning : For solid fuels, thermochemical conversion processes such as combustion and gasification are especially suitable to be carried out in fluidized bed units because of the relatively high mixing rates, fuel flexibility and the possibility to use active bed material to enhance process efficiency. Fuels such as biomass and waste, which are commonly used in fluidized beds, are characterized by volatile contents much higher than what is found in fossil fuels such as coal. LÄS MER
37. A Study on Spray-Guided Stratified Charge Systems for Gasoline DI Engines
Sammanfattning : Innovative technologies are required to meet ongoing challenges to reduce the CO2 emissions from passenger cars and their fuel consumption. Such technologies are usually complex and require detailed analyses to deliver efficient, reliable systems. LÄS MER
38. Numerical Study on Combustion Features of Gasified Biomass Gas
Sammanfattning : There is a great interest to develop biomass combustion systems for industrial and utility applications. Improved biomass energy conversion systems are designed to provide better combustion efficiencies and environmental friendly conditions, as well as the fuel flexibility options in various applications.

39. SOLIDS MIXING IN BUBBLING FLUIDIZED BEDS
Sammanfattning : For solid fuels, thermochemical conversion processes such as combustion and gasification are especially suitable to be carried out in fluidized bed units because of the relatively high mixing rates, fuel flexibility and the possibility to use active bed material to enhance process efficiency. Mixing of fuel is important to ensure complete conversion and reduced emissions of unburnt material. LÄS MER
40. Modeling and Optimal Control for Dynamic Driving of Hybridized Vehicles with Turbocharged Diesel Engines
Sammanfattning : Reducing the fuel consumption of today's vehicle fleet is of great importance due to the environmental impact of using fossil-based fuels. The turbocharged compression ignition (CI) engine is widely used for trucks. The CI engine efficiency is dependent on the operating point, in terms of rotational speed and load. LÄS MER
