Numerical investigation of gas turbine combustion chamber flows

Abstract EN

The paper present mathematical model for two-dimensional axi-symmetric, swirling recirculating, elliptic, turbulent, and reacting flow inside annular combustor.

The present model is restricted to single-phase, kinetically influenced combustion with negligible radiation heat transfer.

The mathematical model comprises differential equation for : Continuity, momentum, stagnation enthalpy, concentration, turbulence energy.

Wall function approach is incorporated to this model to simulate the boundary near wall region.

The simultaneous solution of these equations by means of a finite-difference solution algorithm yields the values of the variable at all internal grid nodes.

All procedure is based on development of a computer program in annular combustor.

The predicted results indicate that the inlet temperature have significant effete on the performance of flow field.

The numerical result shows good agreement behavior of all properties of flow field.
