  2. 1. Design of Thermal Barrier Coatings : A modelling approach

    Author : Mohit Kumar Gupta; Per Nylén; Nicolaie Markocsan; Christer Persson; Lech Pawlowski; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal barrier coatings; Microstructure; Thermal conductivity; Young’s modulus; Interface roughness; Thermally grown oxide; Lifetime; Finite element modelling; Design; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Atmospheric plasma sprayed (APS) thermal barrier coatings (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. TBC is a duplex material system consisting of an insulating ceramic topcoat layer and an intermetallic bondcoat layer. READ MORE

  4. 2. Design of Thermal Barrier Coating Systems

    Author : Nicholas Curry; Per Nylén; Nicolaie Markocsan; Robert Vassen; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coating; Atmopsheric Plasma Spraying; Thermal Conductivity; Thermo-cyclic fatigue; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Thermal barrier coatings (TBC’s) are used to provide both thermal insulation and oxidation protection to high temperature components within gas turbines. The development of turbines for power generation and aviation has led to designs where the operation conditions exceed the upper limits of most conventional engineering materials. READ MORE

  5. 3. State-of-the-art Integrated Refrigeration Systems in Supermarkets : An Energy Efficiency Evaluation Based on Field Measurements Analysis and Computer Simulations

    Author : Mazyar Karampour; Samer Sawalha; Björn Palm; Silvia Minetto; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon dioxide CO2 ; Supermarket; Supermarket refrigeration; Trans-critical cycle; Field meas-urements; Computer simulation; System integration; State-of-the-art; Heat recovery; Air condi-tioning; Reference HFC system; Geothermal energy storage; Energiteknik; Energy Technology;

    Abstract : Supermarkets have become a vital feature of modern society. However, they have significant impact on the environment due to the large amount of refrigerants needed in the refrigeration system, and due to the large energy use in the supermarket, they are the commercial buildings with highest energy intensity.
