  1. 1. Load Shifting and Storage of Cooling Energy through Ice Bank or Ice Slurry Systems : modelling and experimental analysis

    Författare :Marino Grozdek; Per Gunnar Lundqvist; Michael Kauffeld; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; cool thermal energy storage system; ice; modelling; simulation; field measurement; experiment; indirect system; ice-on-coil system; external melt; ice slurry; homogeneous storage; heterogeneous storage; Thermal energy engineering; Termisk energiteknik;

    Sammanfattning : Ice based Cool Thermal Energy Storage (CTES) systems have attracted much attention during last few decades. The reasons are mainly of economical and environmental nature. LÄS MER

  3. 2. Geometry Based Design Automation : Applied to Aircraft Modelling and Optimization

    Författare :Kristian Amadori; Petter Krus; Johan Ölvander; Christopher Jouannet; Bento Silva de Mattos; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Product development processes are continuously challenged by demands for increased efficiency. As engineering products become more and more complex, efficient tools and methods for integrated and automated design are needed throughout the development process. LÄS MER

  4. 3. Membrane emulsification: modelling interfacial and geometric effects on droplet size

    Författare :Marilyn Rayner; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pore geometry; membrane emulsification; Gases; Surface Evolver; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; modelling; Livsmedelsteknik;

    Sammanfattning : Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. LÄS MER

  5. 4. DEM Modelling of Vibratory Screens

    Författare :Ali Davoodi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Validation; Modelling; Screen efficiency; DEM simulation;

    Sammanfattning : In Sweden, about 100 million tons of aggregate is used for road, railway, and concrete every year. Crushing is the main process for producing aggregate material in different fractions. The production process is divided into two sub-processes: comminution or size reduction and classification.

  7. 5. Towards automated conceptual design space exploration

    Författare :Jakob Müller; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Design; Model Abstraction; Function Modelling; Knowledge Based Engineering; Model Based Design; Function-Means Modelling; Geometry Modelling; Design Space Exploration; Product Development; Systems Engineering; Design Automation; Aerospace;

    Sammanfattning : In mature and safety-concerned industries, such as the aerospace industry, product development is often incremental and design solutions are limited to improvements of an existing design. Radical changes to the known product architecture are avoided, for reasons of reliability, lack of technology or lack of design space exploration (DSE) methods. LÄS MER
