Combined POD and Field Analysis of a Turbine Stage with In Situ Reheat

Abstract:

This paper presents a follow-up of the numerical simulation of flow and combustion in a one stage turbine combustor (turbine stage in situ combustion). The main purpose of the simulation is to respond to the questions raised by our previous studies concerning the applicability of the two equations Westbrook-Dryer chemical mechanism (WD2) in their original form. Based on proper orthogonal decomposition analysis, it was found that the reaction rates cannot be reconstructed using only a few modes as all other state variables do. The same injection concept and CAD model as in previous studies is used. We found out that reducing grid size can have a great impact on how well the reaction mechanism correlates with other flow variables.
