SINOPSIS

A semi-implicit large-eddy simulation technique is used to predict transport and infinitely fast reaction processes of an H2/N2-jet injected through a narrow spanwise slot into a subsonic turbulent air flow between isothermal channel walls. The LES technique is based on approximate deconvolution and explicit modelling of the filtered heat release term. Spatial derivatives are computed using sixth order accurate central compact schemes. An explicit fourth-order Runge-Kutta algorithm serves for time-integration. Turbulent inflow conditions are generated by a separate LES of fully developed channel flow and are introduced well upstream of the injection station using characteristic boundary conditions. The complex transport processes in the vicinity of the injection region are highlighted by instantaneous and statistically averaged flow quantities.
