A general framework for the thermodynamics of open systems is presented. The theory is fundamentally based on the generalized balance of mass, which is enhanced by additional surface-°ux and volume-source terms. The presentation highlights the in°uence of the enhanced mass balance on the remaining balance equations. To clarify the impact of the variable reference density, we introduce the notio...

To meet the CO2 reduction targets and ensure sustainable energy supply, the development and deployment of cost-competitive innovative low-carbon energy technologies is essential. To design and evaluate the competitiveness of such complex integrated energy conversion systems, a systematic thermo-environomic optimisation strategy for the consistent modelling, comparison and optimisation of fuel d...

Components in the industry are often exposed to elevated temperatures and high pressures. These conditions cause changes in the microstructure and thermo-mechanical properties of steel components. With the aim to determine the properties of steels after a certain period of operation, thermo-mechanical investigations and microstructure characterization can be made and the results of this investi...

Supercritical CO2 central-receivers must withstand high temperatures and pressures combined with cyclic operation, which makes the solar receiver susceptible to creep-fatigue failure. In this work, a analysis of sCO2 Inconel 740H tubular 2 MWe tower plant has been accomplished study influence tube size on field design. A 2D numerical model that accounts for thermal conduction in both radial cir...
