Abstract

In this study, energy, environment and enviroeconomic analyses are applied to the turbofan engine used in aviation industry. The CO2 emissions of the turbofan engine are calculated and cost of the CO2 emissions for a daily period are evaluated. The energy efficiencies of the overall turbofan engine system, high pressure turbine, low pressure turbine and the combustion chamber are found as 19.7%, 26.2%, 29.2% and 90%, respectively. The CO2 emissions releasing in a day are calculated as 358.9 tonCO2/day, while the CO2 emissions price in a day are calculated as 5742.52 US$/day for the turbofan engine. Also, 3.35 kg carbon dioxide is released into the air as a result of 1 kg of kerosene burning. Environmental and the enviroeconomic results of this study can be useful for developing environmentally sustainable turbofan engines as well as for researches and designers in aviation industry.

Abstract

Increasing global warming concerns are compelling humanity to find alternative fuels to fossil fuels. Ammonia, with its carbon-free structure, can be combusted to produce only water and nitrogen. This study includes exergy analysis–based thermoecologic analysis and life cycle assessment–based environmental pollution cost analysis of a Turbec T100 microturbine. A Turbec T100 microturbine is normally operated with natural gas combustion and is modeled using commercially available software for (1) natural gas; (2) 10% ammonia and 90% natural gas; and (3) 20% ammonia and 80% natural gas mass fractions. The ecologic objective function and ecological coefficient of performance parameters for natural gas combustion are −174.441 and 0.37336, respectively. The 20% ammonia combustion has the best ecologic objective function and ecological coefficient of performance results, which are −156.818 and 0.3986, respectively. The 20% ammonia combustion also decreases the environmental and life cycle–based environmental payback period. However, 20% ammonia combustion slightly increases the payback period of the system. The 20% ammonia has the lowest CO2-equivalent emission rate due to producing the lowest CO2-equivalent emissions during combustion. Finally, 20% ammonia combustion decreases total and specific environmental pollution costs.

Abstract

In this paper, the exergy analysis and environmental assessment are performed to the biodiesel and diesel-fueled engine at full 294 Nm and 1800 r/min. The exergy loss rates of fuels are found as 15.523 and 18.884 kW for the 100% biodiesel (BDF100) (obtained from cooking oil) and Japanese Industrial Standard Diesel No. 2 (JIS#2) fuels, respectively. In addition, the exergy destruction rate of the JIS#2 fuel is found as 80.670 kW, while the corresponding rate of the BDF100 is determined as 62.389 kW. According to environmental assessments of emissions and nanoparticles of the fuels, the biodiesel (BDF100) fuel is more environmentally benign than the diesel (JIS#2) fuel in terms of particle concentration and carbon monoxide and hydrocarbon emissions. So, it is better to use this kind of the 100% biodiesels in the diesel engines for better environment and efficiency in terms of the availability and environmental perspectives.

Abstract

In this paper, the effects of regenerative evaporative coolers on the dry desiccant air cooling system are assessed. Thermodynamic analysis is performed point by point on the unmodified (ɛ = 0.67) and modified (ɛ = 1) regenerative evaporative cooler supported systems. It is found that the effectiveness and efficiency of the system were significantly increased by modification. Effectiveness of the system increases from 0.95 to 2.16 for the wet bulb and from 0.63 to 1.43 for dew point effectivenesses, while the exergy efficiency increases from 18.40% to 41.93%. Exergy and energy performances of the system increase 1.28 times and 0.61 times, respectively. Finally, sustainability is increased by 40% with the modification of the regenerative evaporative cooler. Also, changing the regenerative evaporative cooler of the solid desiccant wheel with the effective one can increase the overall system efficiency and performance without changing the sensible heat and desiccant wheels.
