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 ...
Capturing Cyclic Variability in Exhaust Gas Recirculation Dilute Spark Ignition Combustion Using Multicycle RANS
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dilute combustion is an effective approach to increase the thermal efficiency of sparkignition (SI) internal combustion engines (ICEs). However, high dilution levels typically result in large cycletocycle variations (CCV) ...
Validation of a Three Dimensional Internal Nozzle Flow Model Including Automatic Mesh Generation and Cavitation Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fuel injectors often experience cavitation due to regions of extremely low pressure. In this work, a cavitation modeling method is implemented in the CONVERGE computational fluid dynamics (CFD) code in order to model the ...
High-Fidelity Energy Deposition Ignition Model Coupled With Flame Propagation Models at Engine-Like Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the heightened pressure on car manufacturers to increase the efficiency and reduce the carbon emissions of their fleets, more challenging engine operation has become a viable option. Highly dilute, boosted, and ...
