  1. 1. Temperature analysis of fire exposed load-bearing structures of mono glazed balconies

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Andreas Lilja; [2020]
    Keywords : CFD; FDS; FEM; TASEF; EKS; Eurocode; Simulation; Fire; Balcony; CFD; FDS; FEM; TASEF; EKS; Eurokoderna; Simulering; Brand; Balkong;

    Abstract : Previous to the now acting construction regulations EKS and Eurocode, the fire resistance of the load-bearing structures of mono glazed balconies were designed with a fire test called the SP fire 105. In 2011, when EKS replaced the previous construction regulations called Boverkets konstruktionsregler, BKR, the SP fire 105 was no longer the requirement for mono glazed balconies. READ MORE

  3. 2. Best practice of extracting magnetocaloric properties in magnetic simulations

    University essay from Uppsala universitet/Materialteori

    Author : Johan Bylin; [2019]
    Keywords : Magnetocaloric effect; Thermodynamics; Statistical mechanics; Monte Carlo simulations; Metropolis algorithm; Wang-Landau method; Isothermal change in entropy; Adiabatic change in temperature; Numerical methods; Effective spin models;

    Abstract : In this thesis, a numerical study of simulating and computing the magnetocaloric properties of magnetic materials is presented. The main objective was to deduce the optimal procedure to obtain the isothermal change in entropy of magnetic systems, by evaluating two different formulas of entropy extraction, one relying on the magnetization of the material and the other on the magnet's heat capacity.

  4. 3. EVALUATING THE ORGANIC RANKINE CYCLE (ORC) FOR HEAT TO POWER : Feasibility and parameter identification of the ORC cycle at different working fluid with district waste heat as a main source.

    University essay from Mälardalens högskola/Framtidens energi

    Author : Salman Mohamad; [2017]
    Keywords : Organic Rankine cycle; Recuporator; regenerative; heat-to power; working fluids; low temperature heat; power generation;

    Abstract : New technologies to converting heat into usable energy are constantly being developed for renewable use. This means that more interactions between different energy grid will be applied, such as utilizing low thermal waste heat to convert its energy to electricity. READ MORE

  5. 4. Magnetic Properites in Alloy Systems

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Nanny Strandqvist; [2017]
    Keywords : Magnetocaloric effect; adiabatic temperature change; magnetic entropy change; magnetocaloric materials; magnetic refrigerator;

    Abstract : The attention for materials displaying high magnetocaloric effect (MCE) has grown during the past 30 years. One of the most important properties of MCE is the adiabatic temperature change ( ). The main aim of this work was to develop a method to measure the temperature change ( ) for magnetocaloric materials in a changing magnetic field. READ MORE

  6. 5. Simulation of a lab-scale methanation reactor

    University essay from KTH/Kemiteknik

    Author : Seyedeh Guilnaz Mirmoshtaghi; [2011]
    Keywords : Biogas; methanation reactor; Ruthenium catalyst; isothermal; adiabatic;

    Abstract : By the everyday increasing enthusiasm for using renewable-sustainable sources in energy production area, focusing on one and optimizing it in the best possible way should be of much interest. Biogas production from anaerobic digestion of wastes is a well known energy source which could be applied more efficiently if the CO2portion of it would be upgraded to CH4as well. READ MORE
