In thermal systems for transportation and power generation turbulence and combustion are ubiquitous and very often inextricably coupled processes, down to the smallest scales of continuum mechanics in non-linear fashion. Conventional approaches to Computational Fluid Dynamics (CFD), traditionally ba...

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...

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...

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...
