Determinazione della resistenza termica di pareti da misure in situ: proposta di un metodo di analisis dinamica dei dati registrati
No full textNumerical Investigation of Fluid Flow and Heat Transfer characteristics in cooling of Electrical Motor by Using Nanofluid in the Spiral Channel
No full textIn this paper, properties of flow and heat transfer of nanofluid in the spiral channel used in the cooling system of an electric motor are numerically investigated. The finite element method is used to solve the governing equations. The flow regime is considered as laminar and the base fluid is water. In addition to pure water flow, the effect of adding Aluminium-Oxide nanoparticles in the base fluid on the heat transfer performance of the cooling system is studied. The Reynolds number of the fluid, turns number of the spiral channel, volume fraction of the nanofluid, and pressure drop of the coolant are the most important evaluation parameters of this study. Heat transfer analyses are performed based on computational fluid dynamics and 3D fluid motion analysis
The case study of a photovoltaic plant located at the university of L'Aquila: An economic analysis
No full textSolar energy has contributed significantly to the energy transition towards a low carbon society. Public offices – including universities – are being called to participate in the solar energy transition, as the availability of their rooftops represents an opportunity. The present study aimed at evaluating the economic feasibility of a photovoltaic (PV) plant at the University of L'Aquila, approximately 10 years after an earthquake devastated the region. The reconstruction process is ongoing, and a solar PV plant could potentially move the city in a sustainable direction. The development of sustainability models requires the economic verification of relevant projects and a complete list of indicators for decision-makers. The present work found that a 210 kW PV plant at the University of L'Aquila would reduce emissions by 184.9 t CO2eq/year and generate 1500 € profits for each kW installed; and a 115 kW PV plant would reduce emissions by 101.5 t CO2eq/year and generate profits of 1370 € for each kW installed. The analysis of alternative scenarios gave solidity to the results, confirming the pivotal role of the share of self-consumed energy. Level of insolation and plant size were also found to significantly influence economic performance. Finally, the adoption of a bonus to encourage the production and self-consumption of energy may increase investors’ attention towards environmental issues
