RISLarge Eddy Simulation of High Reynolds Number Nonreacting and Reacting JP 8 Sprays in a Constant Pressure Flow Vessel With a Detailed Chemistry Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In military propulsion applications, the characterization of internal combustion engines operating with jet fuel is vital to understand engine performance, combustion phasing, and emissions when JP8 is fully substituted ...
Development of an Efficient Conjugate Heat Transfer Modeling Framework to Optimize Mixing-Limited Combustion of Ethanol in a Diesel Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mixing controlled combustion of alcohol fuels has been identified as a promising technology based on their low propensity for particulate and NOx production, but the higher heats of vaporization and auto-ignition temperatures ...
Investigating the Combustion Performance of Dual Fuel Combustion With Diesel and Port Injected Hydrogen in A Large Bore Locomotive Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The heavy-duty transportation sector has primarily relied on conventional diesel combustion engines given their reliability and high thermal efficiency relative to spark ignition engines, but increased focus on reducing ...
Development of a Hybrid Lagrangian–Eulerian Model to Describe Spark-Ignition Processes at Engine-Like Turbulent Flow Conditions
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: With the engine technology moving toward more challenging (highly dilute and boosted) operation, spark-ignition processes play a key role in determining flame propagation and completeness of the combustion process. On the ...
Capturing Pressure Oscillations in Numerical Simulations of Internal Combustion Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an earlier publication (Jupudi et al., 2016, “Application of High Performance Computing for Simulating Cycle-to-Cycle Variation in Dual-Fuel Combustion Engines,” SAE Paper No. 2016-01-0798), the authors compared numerical ...
