Lean Methane Mixtures in Turbulent Jet Ignition Combustion System

open access: yesEnergies, 2023
The development of modern vehicle drives is aimed at reducing fuel consumption (i.e., crude oil) and minimizing the exhaust emission of toxic components. One such development is the implementation of a two-stage combustion system. Such a system initiates

The Combustion Characteristics of Double Ramps in a Strut-Based Scramjet Combustor

open access: yesEnergies, 2021
This paper focuses on the influence of ramp locations upstream of a strut-based scramjet combustor under reacting flow conditions that are numerically investigated. In contrast, a computational study is adopted using Reynolds Averaged Navier Stokes (RANS)
