Flashback Detection and Suppression in Reheat Hydrogen Combustor

<br/>This research contributes to addressing climate change challenges through the examination of hydrogen combustion. It investigates the flow dynamics within a simplified model of Ansaldo Energia's GT36 reheat combustor using Large Eddy Simulation (LES) at a high pressure of 20 bar, focusing on the autoignition flashback phenomena observed....

Autoignition and flame stabilisation processes in turbulent non-premixed hot coflow flames

This dissertation examines stabilisation processes in turbulent non-premixed jet flames, created by injecting gaseous fuel into a co-flowing stream of hot, low-oxygen combustion products. Being able to predict whether and how a flame achieves stable and reliable combustion is a matter of great practical relevance, and a challenging scientific...

Optimisation of diesel autoignition tabulation procedures for AVL code "FIRE"

The modifications of existing Diesel auto-ignition tabulation for CFD code AVL "FIRE" will be presented in this paper. Current n-heptane tabulation (used to simulate Diesel behaviour in IC engines) did not include the phenomenon of cool flame ignition. This phenomenon is important since the temperature of the air/fuel mixture is significantly...
