Abstract:The influence of buoyancy on turbulent flame propagation in a Taylor-Couette flow reactor is investigated using dimensional analysis. Based on this analysis, it is concluded that a microgravity environment is needed to fully eliminate buoyancy effects on turbulent-flame structure at high turbulence intensities.
