The effect of Smagorinsky constant.. on gaseous hydrogen/liquid oxygen combustion at supercritical pressures was investigated using large-eddy simulations based on the fourth order compact convection scheme. As.. increased, flame temperatures decreased and coherent turbulent structures and streamwise vortices were weakened. In addition, for.. values greater than 0.1, the kurtosis and skewness values were deviated from the range observed in general turbulent flows. Based on these results
