Simulation study on the effect of fuel-inlet angle on the swirling combustion

Swirling flameless combustion has been highly concerned nowadays due to ultra-low NOx and pollutant emission while delivering low temperature differential and stable combustion. Thanks to the rapid developed computational ability, simulation study has solved higher complexity of computational fluid...
