  1. 1. Numerical and experimental investigation of multiple gas jet flow behaviour in the gas atomization process

    University essay from KTH/Materialvetenskap

    Author : Mahsa Darvishghanbar; [2022]
    Keywords : ;

    Abstract : In several industrial applications, the interaction of supersonic gas jets is encountered such as gas atomization, jet engines and the basic oxygen furnace process. In the gas atomization process, high pressure gases are converted to high velocity gas jets through convergent-divergent nozzles. READ MORE

  3. 2. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Anna Lackner; [2022]
    Keywords : Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

    Abstract : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.

  4. 3. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Emma Ryding; [2022]
    Keywords : Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Abstract : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. READ MORE

  5. 4. Investigating the dynamics controlling dissolved organic matter bioreactivity in agricultural stream water and its link to carbon evasion : A statistical analysis

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Sara Schützer; [2022]
    Keywords : ;

    Abstract : While streams and rivers emit large quantities of CO2 to the atmosphere, both the mechanisms controlling CO2 evasion as well as the sources of CO2 are still uncertain. One potential source of stream CO2 is in-stream degradation of dissolved organic matter (DOM). READ MORE

  6. 5. Aerodynamic Analysis of a Blended Wing Body UAV

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oliver Harrisson; [2022]
    Keywords : Computational Fluid Dynamics CFD ; Blended Wing Body BWB ; ANSYS Fluent; Aeronautics; Unmanned Aerial Vehicle UAV ;

    Abstract : The focus of this thesis is to analyse the flight characteristics of the blended wingbody (BWB) unmanned aerial vehicle (UAV) Green Raven currently being developed by students at the Royal Institute of Technology (KTH) in Stockholm,Sweden. The purpose of evaluating a BWB aircraft is due to its potential increasein fuel efficiency and payload compared to conventional aircrafts which would enable more sustainable flights. READ MORE
