To improve the performance of gas turbine engines

a turbine inter-vane burner (TIB) was designed.The Realizable k-ε turbulent model

probability density function(PDF) combustion model

discreate ordinates(DO) radiation model and discreate phase model (DPM) of FLUENT were used to simulate the turbulent flow and combustion in the burner.It’s observed that the TIB can increase the gas temperature by about 700K with 98.4% combustion efficiency and 4.2% absolute pressure loss.The radial temperature grows linearly with the dimensionless height.The distribution of the velocity

temperature and species are controlled by the degree of mixing of the combustion products and the main flow.Given the radial vane cavity (RVC) plays an important part in improving the outlet temperature profile

its shape deserves more study.Compared to the literature experimental data

it indicates that the mathematical models and numerical methods are reasonable and the numerical results provide an important reference to the design of TIB.
