Supercritical carbon dioxide (sCO2) cycles can achieve higher efficiencies than an equivalent steam Rankine cycle at turbine inlet temperatures (>550 °C) with a compact footprint (tenfold). sCO2 are low-pressure ratio (~4–7), therefore recuperation is necessary, which reduces the heat-addition temperature range. Integration of boiler requires careful management low-temperature heat to plant eff...

For the purposes of this paper, computer-aided physical modelling means a type of modelling in which a computer-aided approach is used, with the basic aim being to maintain the physical structure of a real system or its topology as much as possible in the model. Bond graphs represent a very efficient and traditional approach. However, new, objectoriented and multi-domain tools based on the Mode...

BACKGROUND Percutaneous kyphoplasty (PKP) could achieve rapid pain relief for older patients with osteoporotic vertebral compression fractures (OVCFs). Bone cement in PKP was the key factor keeping the stabilization of the vertebral body. However, the same amount of cement can distribute differently in a vertebral body and can thereby result in different surgery outcomes. Therefore, the volume ...

Abstract The micro gas turbine (MGT) is considered one of the main solutions for future power generation system to provide secure and stable energy. Thanks its multi-fuel capability high values power-to-weight ratio, it a suitable candidate many applications such as Combined Heat Power (CHP) systems, range extenders, auxiliary units. Among these applications, micro-CHP benefits from both electr...

Abstract In the near future, due to growing share of variable renewable energy in electricity mix and lack large-scale storage, coal plants will have shift their role from base-load operation providing fluctuating back-up power. However, current power plants, based on steam Rankine cycle, are not optimized for flexible part-load operation, resulting an intrinsic inadequacy fast load variations....
