Our previous studies on water cooled thorium breeder reactor based on matured pressurized water reactor (PWR) plant technology concluded that reduced moderated core by arranging fuel pins in a triangular tight lattice array and using heavy water as coolant is appropriate for achieving better breeding performance and higher burn-up simultaneously [1–6]. One optimum core that produces 3.5 GW ther...

In this study, nondominated sorting genetic algorithm II (NSGA-II) was used to minimize the cost and carbon emissions of a liquefied natural gas (LNG) dual-fuel ship for given route. This study considered regulations emission control areas (ECA) European Union (EU) Emissions Trading System (ETS) determine optimal speed LNG/oil ratio ship. NSGA-II arrival time at each port LNG usage voyage leg a...

Oxy-fuel combustion is one of the energy utilization technologies for CO2 capture which is ready for commercial demonstration. System steady-state simulation is an effective tool to help us understand the thermodynamic properties and adjust operation conditions of oxy-fuel combustion system. Moreover, dynamic simulation is essential for understanding the dynamic characteristics of the system, w...

Fuel cell-based hybrid cycles that include conventional power generators have been created to modify energy performance and output power. In the present paper, integrated biomass gasification (IBG)-molten carbonate fuel cell (MCFC)-gas turbine (GT) and steam turbine (ST) combined power cycle is introduced as an innovative technique in terms of sustainable energy. In addition, biomass gasificati...

The main objective of this study is to analyze the different ratio of emulsified fuels on the performance, emission and combustion characteristics of four stroke single cylinder kirloskar TV-I direct injection compression ignition engine and compared with diesel fuel under different engine loads with constant engine speed of 1500 rpm. Four kinds of test fuels were prepared namely 80% diesel, 10...

Non-intrusive hydroxyl radical (OH) planar laser-induced fluorescence (PLIF) measurements were obtained in configuration C of the University of Virginia supersonic combustion experiment. The combustion of hydrogen fuel injected through an unswept compression ramp into a supersonic cross-flow was imaged over a range of streamwise positions. Images were corrected for optical distortion, variation...

the primary objective of this work is to introduce a gear ratio selection strategy for a cvt equipped vehicle and show its effectiveness on the fuel consumption reduction. afuzzy control algorithm is designed for this purpose. anonlinear model is developed for simulating the longitudinal vehicle dynamics with accelerator pedal applied by the driver as an input. in order that pedal input values ...

We have developed a sequential power generation system, in which each of stacked enzyme fuel cells was designed to be exposed sequentially to fuel solution by automatically switched fuel flow. The time when the cover was opened by attraction with an external magnet, thereby activating the following cell, was adjustable from a few hours to a few weeks by controlling the weight ratio of Fe3O4 in ...

the waste tyres represent a source of energy and valuable hydrocarbon products. waste tyres were pyrolysed catalytically in a batch reactor under atmospheric pressure. the effects of basic catalysts (mgo and caco3) were studied on the pyrolysis products. the distribution ratio of gas, liquid and char with mgo and caco3 were 24.4:39.8:35.8 wt % and 32.5:32.2:35.2 wt % respectively at 350°c for 2...
