Direct numerical simulation of flame stabilization assisted by autoignition in a reheat gas turbine combustor
A three-dimensional direct numerical simulation (DNS) is performed for a turbulent hydrogen-air flame, represented with detailed chemistry, stabilized in a model gas-turbine combustor. The combustor geometry consists of a mixing duct followed by a sudden expansion and a combustion chamber, which rep...
Direct numerical simulations of premixed and stratified flame propagation in turbulent channel flow
Accurate calculation of gas-liquid-solid flow of CO2 using a WENO method
NOX formation in oxy-fuel combustion of lignite in a bubbling fluidized bed – Modelling and experimental verification
This paper reports results of experimental and numerical studies of NOx formation in a 30 kWth lab-scale bubbling fluidized bed running in oxy-fuel mode. The numerical model is based on the GRI-mech 3.0 mechanism to compute the kinetics of homogeneous reactions of volatiles and char combustion produ...
Premixed hydrogen-air flames interacting with a hydrogen porous wall
A laminar one-dimensional hydrogen-air flame travelling and quenching towards a chemically inert permeable wall (PW) is studied. Hydrogen flows through the wall into the premixed H2-air. The S3D numerical code with detailed chemistry is used. PW results are compared against results of an impermeable...
