  2. 1. Thermal system analysis of embedded building integrated heating - Numerical model and validation of hydronic floor heating systems

    Author : Henrik Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiant heating; floor heating; low temperature hydronic heating; whole building thermal system analysis; Simulink modelling; Building integrated heating;

    Abstract : A numerical simulation tool for building integrated heating (BIH) systems is developed. BIH is defined as a heat supply system that maintains the indoor thermal comfort within acceptable limits by means of a controlled heat supply to the inner of the building envelope/structure.

  4. 2. Magnetic Fields and Induced Power in the Induction Heating of Aluminium Billets

    Author : Mark William Kennedy; Ragnhild E. Aune; Andreas Westermoen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction; heating; billets; coils; magnetic fields;

    Abstract : Induction heating is a common industrial process used for the reheating of billets before extrusion or forging. In this work the influence of the coil and work piece geometry, the effect of the electrical properties of the work piece, and the coil current and frequency, on the magnetic flux density and resulting work piece heating rates were studied.

  5. 3. Numerical Analysis of Evolution Problems in Multiphysics

    Author : Anna Persson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; regularity; generalized finite element; localized orthogonal decomposition; multiscale; finite element method; Thermoelasticity; Riccati equations; thermistor; linear elasticity; Joule heating; parabolic equations; Regularity; generalized finite element; localized orthogonal decomposition; multiscale finite element method; Thermoelasticity; Riccati equations; thermistor; linear elasticity; Joule heating; parabolic equations;

    Abstract : In this thesis we study numerical methods for evolution problems in multiphysics. The term multiphysics is commonly used to describe physical phenomena that involve several interacting models. Typically, such problems result in coupled systems of partial differential equations.

  6. 4. Thermal Modelling of Water-Based Floor Heating Systems - supply temperature optimisation and self-regulating effects

    Author : Henrik Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low temperature heating; self-regulation; predictive control; Floor heating;

    Abstract : Low temperature water-based concrete embedded floor heating systems are studied. The utilisation of low quality heat sources is facilitated by low temperature heating. Theoretical models which describe the transient thermal floor heating operation constitute the basis for the analysis. READ MORE

  7. 5. High temperature properties of polycrystalline Mo(Si,Al)2: compression and oxidation

    Author : Aina Edgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot compression; Mo Si; Al 2; microstructure; heating element; mechanical properties; oxidation;

    Abstract : Electrification of industrial heating processes holds great promise for reducing CO2 emissions. Large furnaces operating at elevated temperatures and in demanding atmospheres are complicated but indeed important to electrify. READ MORE
