Premixed flame ignition is a fundamental issue in combustion. A basic understanding of this
phenomenon is crucial for fire safety control and for the development of advanced …

The impact of chemical reactions at low-temperature (ie, low-temperature chemistry, LTC)
and LTC-induced cool flames on autoignition and premixed flame propagation has been …

Hydrogen is widely perceived as the next generation of clean energy due to its zero carbon
emissions. However, there is an escalating concern regarding hydrogen safety. A deeper …

In this paper, we propose a generalized framework for the derivation of compact difference
schemes for the approximation of an arbitrary order derivative. We formulate a methodology …

Fast and reliable high altitude re-ignition is a critical requirement for the development of
alternative jet fuels (AJFs). To achieve stable combustion, a spark kernel needs to transit in a …

This paper concentrates on the application of passive and active flow control methods to jet
flows. The passive control is obtained by shaping a nozzle cross-section (hexagonal …

In this paper, we analyze the auto-ignition process of hydrogen in a hot oxidizer stream
composed of oxygen–nitrogen and oxygen–water vapor with nitrogen/water vapor mass …

This paper presents an analysis of numerical and modelling issues based on a simulation of
nitrogen-diluted hydrogen lifted flame evolving in a hot co-flow. We apply the large-eddy …

We investigate the dynamics of counter-current reacting flow under varying strengths of the
counterflow and report the occurrence of global instability phenomena. This clarifies the role …

In this paper, we investigate the flow and flame dynamics within a combustion chamber
supplied with nitrogen-diluted hydrogen fuel and air as oxidiser. The chamber is equipped …
