  1. 21. Experimental and Numerical Study on Heat Pipe Assisted PCM Storage System

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Hamidreza Behi; [2015]
    Nyckelord :;

    Sammanfattning : In this study, thermal performance, energy storage and cooling capacity of a heat pipe assisted Phase Change Material (PCM) storage system have been investigated experimentally andnumerically. The heat pipe assisted PCM storage system can store and release energy efficiently. LÄS MER

  3. 22. Comparison of a new, high precision, energy efficient welding method with the conventional Gas Metal Arc Welding on high carbon steel base metal

    Magister-uppsats, Högskolan Väst/Avd för tillverkningsprocesser

    Författare :Aimal Mazidi; [2014]
    Nyckelord :Gas Metal Arc Welding;

    Sammanfattning : CMT+P welding is less susceptible to hot cracking than the MAG welding process due to use of low heat input properties. Solidification cracking was found in all weld specimens that had greater 0.39KJ/mm heat inputs. Cracking occurs because of the contraction stresses generates during cooling. LÄS MER

  4. 23. Analysis of Different Continuous Casting Practices Through Numerical Modelling

    Master-uppsats, KTH/Materialvetenskap

    Författare :Pooria Nazem Jalali; [2013]
    Nyckelord :Continuous casting; numerical modelling;

    Sammanfattning : Fluid flow accompanied by heat transfer, solidification and interrelated chemical reactions play a key role during Continuous Casting (CC) of steel. Generation of defects and production issues are a result of the interaction between mould flux, steel grade and casting conditions. These issues are detrimental to both productivity and quality.

  5. 24. Smoothed Particle Hydrodynamics Simulation for Continuous Casting

    Master-uppsats, KTH/Matematik (Inst.)

    Författare :Adithya Vijaykumar; [2012]
    Nyckelord :;

    Sammanfattning : This thesis proposes a way of simulating the continuous casting process of steel using Smoothed Particle Hydrodynamics (SPH). It deals with the SPH modeling of mass, momentum and the energy equations. The interpolation kernel functions required for the SPH modeling of these equations are calculated. LÄS MER

  7. 25. CFD modeling of heat charging process in a direct-contact container for mobilized thermal energy storage

    Magister-uppsats,

    Författare :Arefeh Hesaraki; [2011]
    Nyckelord :;

    Sammanfattning : Thermal energy storage and phase change materials become increasingly important topics during the last 20 years for heating and cooling purpose in buildings. When there is time delay or mismatch between producing energy and energy demand, thermal energy storage provides a great solution. LÄS MER
