  2. 1. Process Modeling of Combustion and Digesters for On-line Applications

    Author : Anders Avelin; Rebei Bel Fdhila; Erik Dahlquist; Risto Ritala; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The use of biomass has increased in recent years due to the efforts to reduce the high emissions of greenhouse gases, primarily carbon dioxide from combustion of fossil fuels. At the same time industrial processes have become more complex because of increased production rates and profitability requirements. READ MORE

  4. 2. Combined solar and pellet heating systems : Study of energy use and CO-emissions

    Author : Frank Fiedler; Rebei bel Fdhila; Wolfgang Streicher; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heating; pellet heating; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

    Abstract : In this study 4 solar and pellet heating systems have been studied with the help of annual dynamic simulations. Two of the systems comprised a pellet stove and two systems were solar combisystems; one with a store integrated pellet burner, the other with a separate pellet boiler. READ MORE

  5. 3. Fluid Flow and Heat Transfer Simulations for Complex Industrial Applications : From Reynolds Averaged Navier-Stokes towards Smoothed Particle Hydrodynamics

    Author : Md Lokman Hosain; Rebei Bel Fdhila; Konstantinos Kyprianidis; Erik Dahlquist; Hailong Li; Moncho Gomez Gesteira; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Fluid Dynamics; Heat transfer; Industrial applications; Reynolds Averaged Navier-Stokes; Smoothed Particle Hydrodynamics; Energy enginnering; Thermal Management; Process control; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Optimal process control can significantly enhance energy efficiency of heating and cooling processes in many industries. Process control systems typically rely on measurements and so called grey or black box models that are based mainly on empirical correlations, in which the transient characteristics and their influence on the control parameters are often ignored.

  6. 4. TOWARDS ACCELERATED SIMULATIONS FOR FLUID FLOW AND HEAT TRANSFER OF LARGE INDUSTRIAL PROCESSES

    Author : Md Lokman Hosain; Rebei Bel Fdhila; Erik Dahlquist; Hailong Li; Christophe Duwig; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The manufacturing sector is one of the biggest energy consumers. The iron and steel markets in China are growing very fast. Several studies have been performed to evaluate the Chinese steel sector in terms of energy savings and CO2 emissions. READ MORE

  7. 5. Developing the anaerobic digestion process through technology integration

    Author : Johan Lindmark; Rebei Bel-Fdhila; Renaud Escudié; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Process optimization is needed for the development and expansion of the biogas industry and to meet the ever growing demand for methane. This thesis explores process technologies for the development of the anaerobic digestion process and includes pre-treatments, studies on the effects of different mixing modes and evaluation of a water treatment technology.
