RISIncompressible Jet Mixing in Converging-Diverging Axisymmetric Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A test has been made of the constant turbulent Reynolds number hypothesis for a turbulent jet flow in a converging-diverging axisymmetric tube. Using the free turbulent jet as the sole source ...
Tests of Thick Flame Combustion Estimates in a Single-Cylinder Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Estimates of turbulent burning speed, burning zone thickness, and randomness of ignition delay have been incorporated in a model of spark-ignited engine combustion. The estimates have been made ...
Relating Burning Rate and NO Formation to Pressure Development in Two-Stroke Diesel Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A multizone thermodynamic method has been developed to determine combustion rate and NO formation from measured cylinder pressures and performance of two-stroke diesel engines. Integral to the ...
Turbulent Swirling Flow in Short Cylindrical Chambers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbulent swirling flow in a short closed cylindrical chamber has been measured with laser Doppler anemometry. The swirl was generated by a rotating roughened disk and measured during steady ...
Dual-Fueling of a Prechamber Diesel Engine With Natural Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The feasibility of dual-fuel operation with natural gas in a prechamber diesel engine was studied with special emphasis on fuel consumption and cylinder pressure development. The effects of air ...
Turbulent Transient Gas Injections
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compressible transient turbulent gaseous jets are formed when natural gas is injected directly into a diesel engine. Multi-dimensional simulations are used to analyze the penetration, mixing, and ...
A Tabular Taylor Series Expansion Method for Fast Calculation of Steam Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method is proposed for rapid and accurate calculation of steam properties in the regions of the state plane of greatest importance to the steam power industry. The method makes direct ...
Analysis of Combustion in Diesel Engines Fueled by Directly Injected Natural Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A single-cylinder two-stroke (DDC 1-71) diesel engine has been fueled with natural gas directly injected at high pressure into the engine cylinder. Prior to injection of the natural gas, a ...
Rapid and Accurate Calculation of Water and Steam Properties Using the Tabular Taylor Series Expansion Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In applications where both speed and accuracy of computation of thermodynamic properties are important and particularly where the independent variables are not those used in Helmholtz equations, ...
Compressible Flow Ejectors: Part II—Flow Field Measurements and Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study has been made of compressible jet mixing in an axisymmetric ejector of converging-diverging geometry. The mass flow ratio was in the range 1.3 to 2.6 and the nozzle exit ...
