Description

The objective of this effort is to develop a zonal, multi-physics modeling framework for dynamic combustion processes that can capture relevant local physics and simulate system behavior. The primary focus will be on liquid rocket combustors with secondary application to gas turbines. The goal is to obtain an order of magnitude reduction in current simulation time within acceptable error limits. The framework will have sufficient fidelity to be a predictive tool for combustion dynamics, while being computationally tractable for use in a design support role. Our proposed approach demarcates the combustor into separate zones to represent local physics with corresponding local models having requisite fidelity. It will feature CFD modeling coupled with other advanced reduced order models to reduce the computational cost while retaining accuracy. Applications to both single and multi-element injectors will be demonstrated in the Phase I effort.
