Paper Details

In continuous devices such as a gas turbine combustor, there exists a range of complex interacting physics,included are vortex flows with turbulent effect. Rigorous descriptions of these phenomena are, however, either not availableor require mathematical models which are complex for computation, when taken together in the context of multi-dimensionalflows. For these reasons, models of varying degrees of sophistication in the model are continuously increasing withimprovements in numerical methods, computer capabilities and physical understanding. This paper focused on the velocityprofiles, flow distribution and pressure drop in an annular gas turbine combustor. Flow-split through different liner holesand swirler has been estimated. It is seen that percentage flow-split through the outer liner surface holes and inner linersurface holes can be varied by changing the diameter of the liner holes even though the inlet velocity has been maintainedconstant. Various parameters like pressure loss, velocity, mass flow distribution, Mach number, and speed at variouslocations, have been estimated. In addition, the effect of varying the primary inner holes on the cold flow performance of thecombustor has been studied. A 180sector of the combustor has been modeled in Pro-E Wildfire 4.0 and cold flow analysishas been carried out using the software CFD tool 10.
