“…The fuel burn under the TRS might be expected to increase at all altitudes up to 9.2 km with increasing mission distance and mission times, but turboprop‐equipped aircraft require significantly less runway for takeoff and landing than turbofan powered aircraft of the same size [ SKYbrary , ] resulting in decreases of fuel burn at the lowest model layer. Emissions of CO 2 , CO, H 2 O, HC, SO x , and NO x decrease at the majority of the altitudes (see Figure ) because of their decreased emissions from efficient turboprop aircraft engine technology within the combustor compared with that of turbofan engines [ George et al ., ]. At ground level, emissions of CO and NO x decrease by 33 and 29%, respectively, on average between 2005 and 2011.…”

An operational mitigation strategy for commercial aircraft impact on atmospheric composition, referred to as the turboprop replacement strategy (TRS), is described in this paper. The global air traffic between 2005 and 2011 was modeled with the TRS in which turbofan powered aircraft were replaced with nine chosen turboprop powered aircraft on all routes up to 1700 nautical miles (NM) in range. The results of this TRS double the global number of departures, as well as global mission distance, while global mission time grows by nearly a factor of 3. However, the global mission fuel and the emissions of aviation CO2, H2O, and SOx remain approximately unchanged, and the total global aviation CO, hydrocarbons (HC), and NOx emissions are reduced by 79%, 21%, and 11% on average between 2005 and 2011. The TRS lowers the global mean cruise altitude of flights up to 1700 NM by ~2.7 km which leads to a significant decrease in global mission fuel burn, mission time, distance flown, and the aircraft emissions of CO2, CO, H2O, NOx, SOx, and HC above 9.2 km. The replacement of turbofans with turboprops in regional fleets on a global scale leads to an overall reduction in levels of tropospheric O3 at the current estimated mean cruise altitude near the tropopause where the radiative forcing of O3 is strongest. Further, the replacement strategy results in a reduction of ground‐level aviation CO and NOx emissions by 33 and 29%, respectively, between 2005 and 2011.

“…Fallout from these facilities is an additional problem. Although the particulate size ranges from 0.01 to 1 /un, 1 with an average of 0.1 /im, 2 agglomeration does occur 3 and fallout problems exist within a 1 mile radius of the installation. The quantity of fallout is of the order of 600-1000 lb/day for a 17,000 lb thrust engine or 40 Mw peak power unit.…”

“…For PM removal from the emissions of various types of engines including air breathing engines, there are a number of devices such as filters, cyclones, nonthermal plasma and electrostatic precipitators (Babaie et al, 2015;Takasaki et al, 2015;Tian & Ahmadi, 2007;Tu et al, 2012;Zheng et al, 2004;Zhou et al, 2017). Gas turbine engines are a source of PM emissions with diameters less than 2.5 microns, which are subject to regulation under the National Ambient Air Quality Standards (George et al, 1969). Effective pollution control of gas turbine engines has been a major concern in the design of modern aircraft propulsion systems (Schnelle et al, 2015).…”

The dispersion and deposition of nano-particles in laminar flows in the presence of an electric field were studied. The Eulerian-Lagrangian particle tracking method was used to simulate nano-particle motions under the one-way coupling assumption. For nano-particles in the size range of 5 to 200 nm, in addition to the Brownian excitation, the electrostatic and gravitational forces were included in the analysis. Different charging mechanisms including field and diffusion charging as well as the Boltzmann charge distributions were investigated.
