“…In the past decades, considerable studies involving FWI were actively carried out. Most of the previous literatures were mainly focused on the flow field variations [42][43][44][45][46][47][48][49][50] and heat transfer characteristics of FWI. The experimental investigations of the heat transfer mechanism in FWI of laminar and [51][52][53] turbulent flames with different parameters such as fuel types, 54- 56 57-59 [60][61][62] equivalence ratios, Reynolds numbers, nozzle to plate distances [63][64][65] and combustors configurations have been extensively conducted to gain the comprehensive understanding of FWI thermal characteristics.…”

Flame-wall interactions (FWI) as one kind of fundamental combustion phenomenon is universally found in various laboratory and practical combustion devices. It not only affects the combustion and energy conversion efficiency but also induces severe pollutants emissions. This review summarizes the pollutants emission characteristics in FWI from CO and soot aspects. The investigations of CO formation from FWI in various fundamental and practical energy conversion systems with different fuel types, operating conditions, sampling and analyzing methods and etc. are separately discussed. Meanwhile, multiple advanced laser diagnostics techniques are also adopted in different laboratory impinging flames to acquire more accurate and precise measurements of CO distributions in FWI. To gain more knowledge of pollutants emissions in FWI, the behaviors of soot from practical internal engines are observed with the aid of visualization techniques. Studies that utilize different combustion system configurations to modulate soot formation in FWI of practical engines are conducted as well. Recent literature subsequently evaluates the variations of soot morphology and nanostructure in FWI. The characteristics of soot particle size distribution function (PSDF) from FWI are briefly studied via burner-stabilized stagnation (BBS) flames at laboratory scale. The review ends with the unresolved issues for the future research.

“…The velocities of the combustion gases in the combustor are determined with CFD software Fluent, considering a 2-D axisymmetric domain. Turbulence is modeled by using the standard k-ɛ model, with standard wall functions near wall treatment[57,58]. For engineering purposes, this approach saves computational resources, as the viscosity affected near wall region does not need to be resolved.…”

Scramjets are suitable for hypersonic flight, but their use requires the ability to ensure their thermal protection. In this context, a remotely controlled fuel-cooled combustor, suitable for the experimental analysis of the pyrolysis-combustion coupling characterizing a regeneratively cooled combustion chamber when a hydrocarbon propellant is used, has been designed. Similitude rules were used. Ethylene is used as fuel, air as oxidizer, with an equivalence ratio between 1.0 and 1.5 and a fuel injection pressure between 1 and 10 bar. Experiments are realized by varying operating conditions, to determine their impact on combustor heat transfer dynamics. Previous numerical results have been confirmed. A hysteresis effect has been demonstrated. It has been observed that system response time to fuel mass flow rate increases is lower (of about 40 to 50%) than system response time to fuel mass flow rate decreases and that a rise in equivalence ratio from 1.0 to 1.25 produces an increase in system response intensity that is, following the operating conditions, in the range from 90% to 170%. It has also been seen that an increase in equivalence ratio from 1.0 to 1.5 produces a raise of the temperature of the fuel-coolant (of about 40 to 50%), due to the increase in the emissivity of the flame.
