In this work, planar two-photon laser-induced fluorescence (2p-LIF) is applied for the first
time to analyze the fluid dependent spray structure and atomization behavior of water and …

Recent developments in the transition to zero-carbon fuels show that ammonia is a valid
candidate for combustion. However, liquid ammonia combustion is difficult to stabilize due to …

This study is concerned with accurately predicting the subgrid-scale (SGS) stress using an
artificial neural network (ANN) with a linear eddy-viscosity term and a nonlinear term as the …

The transformation of the energy industry into a climate-neutral circular economy is the key
challenge for the 21st century. There is an undeniable need for renewable energy sources …

In gas–liquid two-phase flows, bubble motion significantly affects liquid phase turbulence,
and adding bubble-induced turbulence (BIT) source term is widely used to improve the …

Approximate deconvolution (AD) has emerged as a promising closure for large-eddy
simulation in complex multi-physics flows, where the conventional pure dynamic eddy …

This study proposes a subgrid-scale (SGS) dispersion approach for large-eddy simulation
(LES) of spray. Rather than associating the turbulence correlation timescale used in the …

To improve the fidelity of large eddy simulation (LES) of spray jet dispersion, a dynamic
subgrid dispersion model is proposed based on the Langevin-type stochastic framework to …

Computational singular perturbation (CSP) has been successfully used in the analysis of
complex chemically reacting flows by systematically identifying the intrinsic timescales and …

This dissertation belongs to the research fields of computational combustion physics and
chemistry, with a primary focus on the modeling and simulation of diesel spray assisted …
