Abstract Direct Numerical Simulation (DNS) data obtained by Dave and Chaudhuri (2020)
from a lean, complex-chemistry, hydrogen-air flame associated with the thin-reaction-zone …

Direct numerical simulation (DNS) of laminar lean methane–air and n-heptane–air premixed
flames with high exhaust gas recirculation (EGR) ratios propagating towards inert walls in a …

Data-driven modelling in fluid mechanics is a promising alternative given the continuous
increase of computational power and data-storage capabilities. Highly non-linear flows …

Transport equations for (i) the rate W of product creation and (ii) its Favre-averaged value W˜
are derived from the first principles by assuming that W depends solely on the temperature …

Hydrogen-fueled gas turbines play one of the key roles in future carbon-neutral energy
structure. Due to hydrogen's high flame speed and extreme flame temperature, design of …

A machine-learning-based model is proposed for the wall heat flux in the flame–wall
interaction (FWI). The model is trained by the neural network (NN), and the direct numerical …

Direct numerical simulations of premixed flames propagating and impinging on the wall
surface are performed to investigate the near-wall flame behavior. The evolution of the flame …

We performed direct numerical simulations (DNS) for the two-dimensional (2D) turbulent
ignition of ultra-lean methane–air and n-heptane–air mixtures with a high exhaust gas …

Abstract Effects of pressure and heat loss on the unstable motion of cellular-flame fronts in
hydrogen-air lean premixed flames were numerically investigated. We adopted the reaction …

Although the near-wall turbulence is not fully developed in the engine combustion chamber,
wall heat transfer models based on flow characteristics in fully developed near-wall …
