Abstract

To investigate a trapped-vortex combustor with guide vane and bluff body, different inlet temperature, velocity and equivalence ratio had been changed to study the performance of this combustor. The results show that high inlet temperature and low velocity can reduce the total pressure loss, the change of equivalence ratio has little impact on total pressure loss. Combustor performance of lean oil condition is better than rich oil condition, when the equivalence ratio is less than 1, the combustion efficiency will reach over 99.8%. Each entrance parameters' change can influence the outlet temperature distribution, the OTDF is between 0.06~0.1 in various working conditions.

Key words： guide vane; bluff body; trapped vortex combustor; numerical simulation
