Ignition Delay Time (IDT) plays a significant role in combustion process of advanced power cycles such as direct-fired supercritical carbon dioxide (sCO2) cycle. In this cycle, fuel and oxidizer are heavily diluted with carbon dioxide (CO2) and autoi

Laser ignition of premixed flames is studied in supersonic channel flow. Breakdown of natural gas air kernels occurs via a focused frequency-doubled (532 nm) Nd:YAG laser. A calibrated double photodiode energy measurement system is employed to differ

Premixed flame kernels exposed to a mean expanding supersonic channel flow are examined using experiments and large-eddy simulations. Four cases, spanning three Mach numbers and two equivalence ratios, are explored. Numerical results are processed si

The directly fired supercritical carbon dioxide (sCO2) power cycle has high efficiency while allowing nearly complete carbon dioxide (CO2) capture. The operating conditions of sCO2 power cycle (100–300 bar) combustors are dramatically different fro

We present results from studies of freely expanding flames in a unique small-scale convective facility for different free-stream initial conditions, characterized by Taylor-Reynolds numbers in the range of R e λ g = 179 − 395 (using the streamwise

It is unclear whether turbulent flame speed scalings established in low speed regimes are applicable to supersonic flames. To investigate this question, the canonical flame kernel is investigated in a scramjet-like channel having a one degree wall di

We demonstrate a small-scale channel flow facility with passive and active turbulence generators for the study of spherically expanding turbulent flames. Traditionally, this canonical flame type is investigated in stagnant cylindrical combustion cham
