RISPreliminary Investigation of Cycle-to-Cycle Variations in a Nonair-Breathing Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of nonair mixtures on cycle-to-cycle variations of cylinder pressure characteristics was investigated experimentally with an indirect-injected (IDI) diesel engine. The engine intake ...
The Influence of Additives on the Temperature, Heat Transfer, Wear, Fatigue Life, and Self Ignition Characteristics of a 155 mm Gun
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The temperature and heat transfer per round was measured at the bore surface of a 155 mm AS90 extended range ordnance. The ammunition was fired with and without wear-reducing additive and the ...
Air Entrainment Processes in a Circular Plunging Jet: Void-Fraction and Acoustic Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Circular plunging jets were studied by both void fraction and acoustic techniques. There were two aims: to measure the structure of the jet flow and its regimes as a function of jet speed ...
The Influence of the El Niño–Southern Oscillation on Cloud-to-Ground Lightning Activity along the Gulf Coast. Part II: Monthly Correlations
Publisher: American Meteorological Society
Abstract: The El Niño?Southern Oscillation (ENSO) cycle is known to influence weather and climate along the Gulf Coast region, causing anomalously high precipitation during El Niño winters. This region is also known for having the ...
Preliminary Investigation of Direct Injection Neat n Butanol in a Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characteristics of combustion, emissions, and thermal efficiency of a diesel engine with direct injection (DI) neat nbutanol were investigated. The engine ran at a load of 6.5–8.0 bar indicated mean effective ...
Dynamical Control of the Mesosphere by Orographic and Nonorographic Gravity Wave Drag during the Extended Northern Winters of 2006 and 2009
Publisher: American Meteorological Society
Abstract: version of the Canadian Middle Atmosphere Model (CMAM) that is nudged toward reanalysis data up to 1 hPa is used to examine the impacts of parameterized orographic and nonorographic gravity wave drag (OGWD and NGWD) on the ...
The Climate Impact of Past Changes in Halocarbons and CO2 in the Tropical UTLS Region
Publisher: American Meteorological Society
Abstract: chemistry?climate model coupled to an ocean model is used to compare the climate impact of past (1960?2010) changes in concentrations of halocarbons with those of CO2 in the tropical upper troposphere and lower stratosphere ...
Heat Release Characteristics of a Volatile, Oxygenated, and Reactive Fuel in a Direct Injection Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compression ignition (CI) diesel engines offer power-dense solutions for heavy-duty vehicles. The purpose of combustion management for diesel engines primarily concerns the balance of high efficiency and low emissions. ...
An Enabling Study of Low Temperature Combustion With Ethanol in a Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous research indicates that the low temperature combustion (LTC) is capable of producing ultralow nitrogen oxides (NOx) and soot emissions. The LTC in diesel engines can be enabled by the use of heavy exhaust gas ...
Separating the Dynamical Effects of Climate Change and Ozone Depletion. Part I: Southern Hemisphere Stratosphere
Publisher: American Meteorological Society
Abstract: A version of the Canadian Middle Atmosphere Model that is coupled to an ocean is used to investigate the separate effects of climate change and ozone depletion on the dynamics of the Southern Hemisphere (SH) stratosphere. ...
