  1. 1. Model of Thermal EHL Based on Navier-Stokes Equations : Effects of Asperities and Extreme Loads

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Marko Tošić; [2019]
    Keywords : ;

    Abstract : A common approach in numerical studies of elastohydrodynamic lubrication (EHL) is based on solving the Reynolds equation that governs pressure distribution in thin lubricant films. The Reynolds equation is derived from the Navier-Stokes equations by taking assumptions that are considered valid when the thickness of the lubricant film is much smaller than its length. READ MORE

  2. 2. Thermal Loads in Space Turbines

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Emily Chen; [2019]
    Keywords : ;

    Abstract : Prediction of thermal loads within cavities in space turbine, has as been a challenging task  in aspects of achieving accurate and reasonable estimations that are crucial for design concepts. The difficulty lies within the turbulent flow and its thermal interaction with the structure inside such section. READ MORE

  3. 3. Global stability of high-rise buildings on foundation on piles

    University essay from KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

    Author : Husein Dhorajiwala; Agnieszka Owczarczyk; [2018]
    Keywords : High-rise buildings; Tall buildings; Buckling; Global Stability; Foundation; Straight piles; Inclined piles;

    Abstract : In Sweden as well as other countries the trend of building higher is more and more popular. The global stability of tall buildings is a very important aspect that has to be taken into account while designing. Foundation on piles, that is common in Sweden, reduces the global stability compared to foundation directly on bedrock. READ MORE

  4. 4. Sensitivity analysis of important parameters affecting daylight - Assessment of a typical cellular office in Sweden

    University essay from Lunds universitet/Energi och ByggnadsDesign

    Author : Danai Vogiatzi; [2018]
    Keywords : daylight; office; dynamic metrics; static metrics; orientation; glazing transmittance; surface reflectance; window size; shape; position; number and niche; obstruction angle; sensitivity analysis; Technology and Engineering;

    Abstract : The objective of this thesis was the impact evaluation of several parameters affecting daylight conditions in a typical cellular office in Lund, Sweden. The research approach that was followed consisted of three distinct steps; the literature review in order to specify the dependent and independent variables of the study, the simulation part to produce daylight performance data and the graphical analysis as interpretation of the data produced.

  5. 5. Modeling of Effective Leaf Area Index

    University essay from SLU/Dept. of Forest Resource Management

    Author : Lina Selin; [2018]
    Keywords : Sentinel-1; tree species; random forest; linear discriminant;

    Abstract : Mapping of e�ective leaf area index (LAIe) over the Swedish boreal forest test site Krycklan (64°N19°E) was performed using ground-based �eld estimates of LAIe and remote sensing data sources. The LAIe data were collected 2017 and 2018 using the LAI-2200 Plant Canopy Analyzer and its later version LAI-2200C Plant Canopy Analyzer. READ MORE
