  1. 1. Mixing Processes for Ground Improvement by Deep Mixing

    Author : Stefan Larsson; KTH; []
    Keywords : Deep Mixing; Lime cement columns; Mixing mechanisms; Mixture quality; Field test; ANOVA; Variance reduction.;

    Abstract : The thesis is dealing with mixing processes havingapplication to ground improvement by deep mixing. The mainobjectives of the thesis is to make a contribution to knowledgeof the basic mechanisms in mixing binding agents into soil andimprove the knowledge concerning factors that influence theuniformity of stabilised soil.

  2. 2. Turbulent jets in confined spaces : application in mixing ventilation: experimental and numerical studies

    Author : Taghi Karimipanah; Mats Sandberg; H. A. Awbi; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent; wall jet; impinging jet; free jet; confinement effect; pressure; throw; experimental; numerical; corner; momentum; mixing ventilation;

    Abstract : The basis of mixing ventilation is the airflow supply to the room by means of jets initiatedfrom the ventilation diffusers. To avoid the draught problem, the design of mixing ventilationmakes uses the throw term, which is defined as the distance to the supply air terminal inwhich the jet centreline mean velocity is decreased to a given value.

  3. 3. Ocean mixing and polynyas at Maud Rise, Weddell Sea

    Author : Martin Mohrmann; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Weddell Sea; Southern Ocean; Maud Rise; Polynya; Frontal mixing;

    Abstract : The Weddell Sea Polynya is an intermittent, ice free area in the marginal ice zone with an extent of up to 350 000 km². It was first observed by satellites in the winter seasons of 1974-1976. In 2016 and 2017, an open-ocean polynya opened over the Maud Rise oceanic plateau in the eastern Weddell Sea, which was the largest since the 70’s. READ MORE

  4. 4. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes

    Author : Christian Nohr; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Water and Heat budgets; Deep-water mixing; Internal Wavedrag; Dynamical Sea Ice production; Sea Ice dynamics;

    Abstract : This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. READ MORE
