Abstract

The applicability of Conditional Source-term Estimation (CSE) for high-pressure combustion applications is investigated within the context of Reynolds Averaged Navier-Stokes equations (RANS). The tabulation of the conditional chemical source-terms, typically done using a trajectory generated low-dimensional manifold, presents a more constrained region of physical realizability, which imposes new constraints on the tabulation. Various approaches are presented and discussed. The applicability of CSE is then tested on a high-pressure methane-oxidizer combustor.
