International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023 A reliable combustion monitoring system is essential to satisfy global carbon neutrality trends. As the concentrations of emissions and flame stability are associated with the air–fuel ratio, the equivalence ratio should be continuously evaluated. In this study, a deep neural network‐ (DNN‐) based regression model is proposed to predict the equivalence

Sizing of scramjet vehicles [PDF]
Progress in Propulsion Physics, 2011 The current European project LAPCAT II has the ambitious goal to de¦ne a conceptual vehicle capable of achieving the antipodal range Brussels Sydney (∼ 18,000 km) in about 2 h at Mach number Ma = 8. At this high speed, the requirement of high lift to drag (L/D) ratio is critical to high performance, because of high skin friction and wave drag: in fact,
