Exergy Analysis of Complex Ship Energy Systems
With multiple primary and secondary energy converters (diesel engines, steam turbines, waste heat recovery (WHR) and oil-fired boilers, etc.) and extensive energy networks (steam, cooling water, exhaust gases, etc.), ships may be considered as complex energy systems. Understanding and optimizing such systems requires advanced holistic energy modeling. This modeling can be done in two ways: The ...
متن کاملExergy analysis of incremental sheet forming
Research in the last 15 years has led to die-less incremental forming processes that are close to realization in an industrial setup. Whereas many studies have been carried out with the intention of investigating technical abilities and economic consequences, the ecological impact of incremental sheet forming (ISF) has not been studied so far. Using the concept of exergy analysis, two ISF techn...
متن کاملExergy Analysis of Flat Plate Solar Collectors
This study proposes the concept of the local heat loss coefficient and examines the calculation method for the average heat loss coefficient and the average absorber plate temperature. It also presents an exergy analysis model of flat plate collectors, considering non-uniformity in temperature distribution along the absorber plate. The computation results agree well with experimental data. The ...
متن کاملExergy Analysis of a Compartment Fire
A thermodynamic model of a compartment fire with one state variable (corresponding to the dimensionless temperature of the smoke layer) based on energy conservation is studied from the point of view of the Second Law (exergy analysis). To define the exergy rate of the process, a novel concept of mean thermodynamic temperature is introduced for the smoke layer. This parameter is the equivalent o...
متن کاملExergy Analysis of a Co2 Thermosiphon
Engineered geothermal systems (EGS) present an opportunity to expand the implementation of geothermal power. There has been some interest in the possible application of CO2 as a heat extraction fluid in these systems instead of water, due to a variety of inherent benefits, including being a nonpolar fluid, low viscosity at the temperatures and pressures within the reservoir and a large buoyancy...
