Air Pollution Emissions From Jet Engines

Nanoparticle Emissions from Engines

Recently concerns about possible increases in emissions of ultrafine and nanoparticles and their environmental impact have been voiced. A major problem with assessing the significance of such emissions is that, unlike the carbonaceous soot particles associated with older Diesel engines, many of these particles are not formed in the engine but instead by gas-to-particle conversion processes from...

Cooking Up Indoor Air Pollution: Emissions from Natural Gas Stoves

Cooking Up Indoor Air Pollution Emissions from Natural Gas Stoves Natural gas cooking appliances, which are used by a third of U.S. households, can contribute to poor indoor air quality, especially when used without an exhaust hood. Gas stoves emit nitrogen dioxide (NO2), carbon monoxide (CO), and formaldehyde (HCHO), each of which can exacerbate various respiratory and other health ailments. I...

Off-Design Performance Prediction of Jet Engines

In this paper it is attempted to predict the off-design performance of a jet engine. After a review of the governing equations, the off-design performance is investigated by two methods. In the first method, the component characteristic curves of the Gas Turbines are used. In the second method some design point parameters and the reference state conditions are employed. The results obtained by ...
