Engine combustion characteristics and misfire phenomena in a turbocharged direct-injection
gasoline engine with a pre-chamber are studied through multi-dimensional modeling of the …

A discussion of modeling passive scalar transport in turbulent flows is given. Several
methods employed to close the scalar-flux term⟨ u′ ϕ′⟩ that arises during Reynolds …

The computational fluid dynamics-based design of next-generation aeronautical combustion
chambers is challenging due to many geometrical and operational parameters to be …

The accurate prediction of the fluid dynamic conditions at the exit of gas turbine combustors
are of paramount importance in the aero-thermal design of the aero-engine. In fact, both the …

The target of net-zero emissions set by the 2015 Paris Agreement has strongly
commissioned the energy production sector to promote decarbonization, renewable sources …

The adoption of lean burn combustion to limit NOx emissions of modern aero-engines
imposes a drastic reduction of air dedicated to cooling combustor dome and liners. In the …

The Reynolds analogy concept has been used in almost all turbulent reacting flow RANS
(Reynolds-averaged Navier–Stokes) simulations, where the turbulence scalar transfers in …

Parametric large eddy simulations (LES) of a supersonic lifted hydrogen flame are reported.
The emphases are on two aspects: impacts of (1) Lewis number (Le i of the ith species) and …

Increasingly stringent limitations imposed on aircraft engine emissions have led many
manufacturers toward lean combustion technology, which involves a relevant increase in …

A slightly heated turbulent round jet at high Reynolds number (Re D= 1.5× 10 5) was studied
using simultaneous Laser Doppler Velocimetry and cold wire thermometry measurements …
