Modern gas turbines need to fulfil increasingly stringent emission targets on the one hand and exhibit outstanding operational fuel flexibility other. Ansaldo Energia GT26 GT36 turbine models address these requirements by employing a combustion system in which two lean premixed combustors are arranged series. Due high inlet temperatures from first stage, second combustor stage predominantly rel...

Numerical simulations are performed to study the mechanism of deflagration detonation transition (DDT) in a pre-/main-chamber combustion system with stoichiometric ethylene–oxygen mixture. A Godunov algorithm, fifth-order space, and third-order time, is used solve fully compressible Navier–Stokes equations on dynamically adapting mesh. single-step, calibrated chemical diffusive model described ...
