Explicit Filtering LES for turbulent premixed flames
Large eddy simulations of a premixed, turbulent, methane-air round jet flame at an equivalence ratio of 0.8 and unburnt gas temperature of 800 K are performed using Explicit Filtering LES (EFLES) method. The nominal inflow ... -
Exploration And Assessment of HCCI Strategies for a Multi-Cylinder Heavy-Duty Diesel Engine
(2017-10-17)Homogeneous Charge Compression Ignition (HCCI) combustion is an alternative combustion mode in which the fuel is homogeneously mixed with air and is auto-ignited by compression. Due to charge homogeneity, this mode is ... -
