  2. 16. Optimization and Model Validation of Transonic Compressors

    Author : Lars R Ellbrant; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compressor; optimization; design; metamodels; CFD; validation; multiobjective;

    Abstract : Economical aspects such as reduced specific fuel consumptions and ever growing environmental requirements on emissions and percieved noise levels, are the major drivers in the search for improvement of aircraft engines. For turbofan engines, the global trend is towards higher efficiency which is accomplished by increasing component efficiencies, the bypass ratio and overall pressure ratio while keeping the engine weight low.

The thesis addresses to what extent the digitalized material is used, and how findable it is on the web. READ MORE

  5. 18. Tree Models for Design Space Exploration in Aerospace Engineering

    Author : Siva Krishna Dasari; Abbas Cheddad; Lars Lundberg; Pawel Herman; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A crucial issue in the design of aircraft components is the evaluation of a larger number of potential design alternatives. This evaluation involves too expensive procedures, consequently, it slows down the search for optimal design samples. READ MORE

  6. 19. Particles and unregulated emissions from heavy-duty engines

    Author : Kent Nord; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Nowadays, the diesel engine is a widely used power source with complex emissions. In order to find out the impact from diesel exhaust on health and environment, both regulated and unregulated exhaust gas emission have to be evaluated. READ MORE
