Turbulent flow in a boundary layer with injection of hydrogen through
a permeable plate into an external air flow is modeled. To calculate
turbulence characteristics the Lam-Bremhorst modification of the
k - 
model is employed. Calculations are made both with and without
account for the non-unity of the Lewis number. In determining the
concentrations of the intermediate and end combustion products and
the temperature the assumption of chemical equilibrium is made. The
obtained distribution of turbulent pulsations allows the conclusion
of flow laminarization under combustion conditions to be made.
