  2. 1. On the Late Saalian glaciation : A climate modeling study

    Author : Florence Colleoni; Martin Jakobsson; Johan Nilsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate modeling; Eurasian ice sheet; Quaternary; Saalian; surface mass balance; SST; Earth sciences; Geovetenskap; Marine Geoscience; marin geovetenskap;

    Abstract : This thesis focuses on the glaciation of the Late Saalian period (160 -140 ka) over Eurasia. The Quaternary Environment of the Eurasian North (QUEEN) project determined that during this period, the Eurasian ice sheet was substantially larger than during the entire Weichselian cycle and especially that of the Last Glacial Maximum (21 ka, LGM).

  4. 2. Near-Field Study of Multiple Interacting Jets : Confluent Jets

    Author : Shahriar Ghahremanian; Bahram Moshfegh; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple interacting jets; confluent jets; axisymmetric round jet; Low Reynolds number jet; Particle Image Velocimetry PIV ; Laser Doppler Anemometry LDA ; Hot-Wire anemometry HWA ; RANS turbulence models; SST ? − ?; Low Reynolds ? − ?; Response Surface Method;

    Abstract : This thesis deals with the near-field of confluent jets, which can be of interest in many engineering applications such as design of a ventilation supply device. The physical effect of interaction between multiple closely spaced jets is studied using experimental and numerical methods. READ MORE

  5. 3. Jet Impingement and Infrared Heating of Cylindrical Foods. Flow and Heat Transfer Studies

    Author : Eva Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Gaser; fluid dynamics; plasmas; Gases; RSM; CFD; inverse heat transfer; jet impingement heat transfer; infrared heating; termodynamik; Food and drink technology; Livsmedelsteknik; PIV; SST; food; cylinder;

    Abstract : Rapid heat transfer methods such as jet impingement and infrared radiation can be used to speed up thermal processing in the food industry. The heating rate affects important food characteristics, such as colour. READ MORE

  6. 4. Modelling of Jet impingement Heat Transfer for Cooling of Cylindrical Foods

    Author : Eva Olsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple jets; Nusselt number; cooling; sinle jet; Jet impingement heat transfer; CFD; cylinder; SST; food;

    Abstract : Cooling is an energy consuming operation in the food industry. Rapid cooling reduces the risk of growth of micro-organisms, improves the quality of the food product and increase the production rate... READ MORE

  7. 5. CFD Modeling of Combustion in Flexi-Fuel Burners at Gas Turbine Conditions

    Author : Abdallah Abou-Taouk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAS-SST; Global reaction mechanism; CFD; LES; RANS; Combustion; PSR; Chemistry;

    Abstract : The main source of energy in the nearest future will come from fossil fuels. Increasing demands on environmentally friendly energy conversion implies that pollutants, such as CO and NOx, need to be reduced. READ MORE
