Confined turbulent swirling combustion data obtained from gas chromatograph, gas analyzers, thermocouples and hot wire anemometer for a wide range of operating conditions are analyzed numerically. The effect of swirling flow, inlet velocity and equivalence ratio on different parameters with and without secondary air are discussed and analyzed. The obtained experimental data facilitated better and deep understanding of complicated problems associated with swirl reacting flow and provided in the same time generalized relations for the turbulent viscosity and velocity of chemical reaction required for the development of numerical prediction methods.
