RISBayesian Data Assimilation in Cold Flow Experiments on an Industrial Thermoacoustic Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We assimilate experimental data from nonreacting flow in the SCARLET (SCaled Acoustic Rig for Low Emission Technologies) test rig using physics-based Bayesian inference. We model the complex geometry of the combustor with ...
A Hybrid, Runtime Coupled Incompressible CFD-CAA Method for Analysis of Thermoacoustic Instabilities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermoacoustic instabilities in gas turbine engines are of increasing interest for design of future low-emission technology combustors. Numerical methods used to predict thermoacoustic instabilities often employ either ...
Model-Based Inference of Flame Transfer Matrices From Acoustic Measurements in an Aero-Engine Test Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flame dynamics, represented as a flame transfer matrix (FTM), is not directly measurable in test rigs and must be deduced from transfer matrix measurements of the combustion system. The burner-flame transfer matrix (BFTM) ...
