  1. 1. Influence of nitrocarburization on the thermomechanical fatigue properties of ductile iron for exhaust components : Analysis and comparisons of TMF-properties

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Karl Larsson; [2019]
    Keywords : Thermo-mechanical fatigue; low cycle fatigue; thermal strain; ductile cast iron; nitrocarburizing;

    Abstract : New stricter environmental legislation requires lower emissions and fuel consumption of automotive engines. Therefore the fuel efficiency must be increased but this leads to higher loads in the engine. As for the exhaust system it is affected by higher thermomechanical loads. READ MORE

  2. 2. Experimental Study of Heat Transfer Coefficient and Film Cooling Effectiveness

    University essay from KTH/Energiteknik

    Author : Ke Li; [2019]
    Keywords : ;

    Abstract : This thesis investigates the possibility to evaluate the film cooling thermal performance on flat plate using Thermochromic Liquid Crystal. After an introduction of the basic concept and background of gas turbine blades film cooling and Thermochromic Liquid Crystal, a thorough explanation of four methods is presented. READ MORE

  3. 3. HYDROGEN-FIRED GAS TURBINE FOR POWER GENERATION WITH EXHAUST GAS RECIRCULATION : Emission and economic evaluation of pure hydrogen compare to natural gas

    University essay from Mälardalens högskola/Framtidens energi; Mälardalens högskola/Framtidens energi

    Author : Nemir Gibrael; Hamse Hassan; [2019]
    Keywords : harmful emission; natural gas; fuel reforming process; hydrogen fired gas turbine; exhaust gas recirculation; techno-economic analysis;

    Abstract : The member states of European Union aim to promote the reduction of harmful emissions. Emissions from combustion processes cause effects on human health and pose environmental issues, for example by increasing greenhouse effect. READ MORE

  4. 4. HPDC Die design for Additive Manufacturing : Simulation and Comparison of Thermal Stresses in HPDC die designed for Additive Manufacture

    University essay from Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design; Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design

    Author : Ambareeksh Tharayil Pradeep; Mohammadali Baradaran; [2019]
    Keywords : High Pressure Die Casting; Additive Manufacturing; Finite Elements Analysis;

    Abstract : Additive manufacturing has a great potential to benefit die manufacture by shortening the lead time considerably and lifting the limitations on design complexity imposed by conventional manufacturing techniques. However, AM has its own requirements that together are known as Design for Additive Manufacturing and account for the process limitations. READ MORE

  5. 5. Simulation of Hardening of the MahanaKhon Tower Mat Foundation

    University essay from KTH/Betongbyggnad

    Author : Zakaria Kazi-tani; [2019]
    Keywords : Hydration; MahanaKhon tower; mat foundation; young concrete; temperature development; thermal stresses; cracking; fly ash; finite element analysis; COMSOL Multiphysics; Hydratation; MahanaKhon tower; bottenplatta; ung betong; temperaturutveckling; termiska spänningar; sprickbildning; flygaska; finita elementanalys; COMSOL Multiphysics;

    Abstract : Cement hydration is the result of a series of simultaneous chemical reactions occurring during the production of concrete. An excessive amount of heat is generated, which consequently may give rise to thermal stresses and cause early age cracks in concrete that may affect its structural integrity, and load bearing capacity.
