    Sammanfattning : Laser based optical diagnostic methods are routinely used in combustion research. Many of the more common approaches are based on illuminating a cross-section of the sample with a thin laser sheet. For example, by targeting an electronic transition in a molecule, its concentration within the plane illuminated by the laser sheet can be deduced. LÄS MER

  3. 7. A study of turbulence and scalar mixing in a wall-jet using direct numerical simulation

    Författare :Daniel Ahlman; Arne V. Johansson; Lars-Erik Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningmekanik; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Direct numerical simulation is used to study the dynamics and mixing in a turbulent plane wall-jet. The investigation is undertaken in order to extend the knowledge base of the influence of the wall on turbulent dynamics and mixing. The mixing statistics produced can also be used to evaluate and develop models for mixing and combustion. LÄS MER

  4. 8. Numerical predictions and measurement of non-isothermal airflows : evaluation of buoyant wall jets and airflow through large openings

    Sammanfattning : How can we attain a good indoor climate and at the same time reduce energy consumption? These issues are of particular interest in countries with cold climates, where the need for heating is large. It is important to design a HV AC (Heating, Ventilation and Air Conditioning) system that achieves a desirable indoor climate, where discomfort due to draft and thermal discomfort is avoided. LÄS MER
