1. Conceptual metaphors in learning and teaching entropy : adopting a cognitive semantic approach in science education research
University dissertation from Linköping : Linköping University Electronic PressAbstract : Over the last 20 years there has been an extensive amount of research on science learning conducted from a “knowledge-in-pieces” or “resources” perspective. One of the main goals of that research has been to identify and characterize available cognitive knowledge resources that can be productive components of scientific understanding. READ MORE

2. Analogical reasoning in science education - connections to semantics and scientific modelling in thermodynamics
University dissertation from Linköping : Linköping University Electronic PressAbstract : Analogiskt tänkande är en central kognitiv förmåga som vi använder i vardagslivet, såväl som i mer formella sammanhang, såsom i forskning och undervisning. Föreliggande avhandling behandlar hur analogier och analogiskt tänkande, uppmärksamhet på semantik och förståelse för vetenskaplig modellering kan användas för att hantera utmaningar i naturvetenskapsundervisningen, särskilt inom området termodynamik.

3. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors
University dissertation from Mrs Gunvi Andersson, Div. Heat Transfer, Box 118, 22100 Lund, SwedenAbstract : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. READ MORE

4. On the Analysis and Fault-Diagnosis Tools for Small-Scale Heat and Power Plants
University dissertation from Department of Heat and Power Engineering, Lund universityAbstract : The deregulation of the electricity market drives utilities and independent power producers to operate heat and power plants as profit centers. In order to keep the economic margins on the credit side, the preferred measures have been to improve the electrical efficiency through changes in the hardware and boost the overall efficiency through e.g. READ MORE

5. On Radiative Heat Transfer Modeling with Relevance for Combustor and Biomass Furnaces
University dissertation from Lund University (Media-Tryck)Abstract : Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. READ MORE
