  2. 1. Driving rain tightness, intrusion rates and phenomenology of leakages in defects of façades: A new calculation algorithm

    Author : Lars Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; façade details; rain resistance; window-wall interface; EN 12865; protrusion; deficiency; catch area; water flow; obstacle; fenestration; dam; driving rain; water leakage; leakage flow; hole;

    Abstract : This thesis presents the driving rain tightness of façades with façade details as well as the water leakage flows that can be expected. Furthermore, it describes the key mechanisms for water leakage in defects in the outermost layer of external walls. READ MORE

  4. 2. Process Models for CO2 Migration and Leakage : Gas Transport, Pore-Scale Displacement and Effects of Impurities

    Author : Farzad Basirat; Auli Niemi; Karsten Jensen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geological Carbon Storage; CO2 leakage; Field experiment; Laboratory experiment design; Multi-phase flow; Heterogeneity; Wettability; Pore-scale modeling; Impurity gases; Hydrology; Hydrologi;

    Abstract : Geological Carbon Storage (GCS) is considered as one of the key techniques to reduce the rate of atmospheric emissions of CO2 and thereby to contribute to controlling the global warming. A successful application of a GCS project requires the capability of the formation to trap CO2 for a long term. READ MORE

  5. 3. Numerical Simulation of Some Heat Transfer and Fluid Flow Phenomena for Gas Turbine Blades and a Transonic Turbine Stage

    Author : Fadil Mumic; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; plasmas; Gaser; fluid dynamics; Gases; transonic; numerical; heat transfer coefficient; shroud surface; squealer blade tip; flat blade tip; leakage flow; Termisk teknik; termodynamik; turbulence modeling;

    Abstract : With the attempts to achieve higher thermal efficiency, turbine blades are exposed to very high temperature gases and may undergo severe thermal stress and fatigue. Thus, in order to develop optimal cooling strategies and reduce the heat transfer it is important to obtain a good understanding of both the complex flow field and the heat transfer characteristics in turbine rotor/stator hot-gas passages.

  6. 4. MAC, A Verified Information-Flow Control Library

    Author : Marco Vassena; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Haskell; NonInterference; Agda; Functional Programming; Information-Flow Control;

    Abstract : Information Flow Control (IFC) is a language-based security mechanism that tracks where data flows within a program and prevents leakage of sensitive data. IFC has been embedded in pure functional languages such as Haskell, in the form of a library, thus reducing the implementation and maintenance effort and fostering a secure-by-construction programming-model.

  7. 5. On the inception of leakage : Effect of hydrostatic pressure on the sealing interface

    Author : De Huang; Andreas Almqvist; Roland Larsson; Xiang Yan; Alessandro Ruggiero; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static seal; contact mechanics; hydrostatic; critical pressure; leakage; Maskinelement; Machine Elements;

    Abstract : As the move towards sustainability continues,  attention needs to be paid to the development of new machinery with high performance and low environmental impact. It places increasing demands on low/zero-emission sealing with a long lifetime. READ MORE
