Registration-based model reduction of parameterized PDEs with spatio-parameter adaptivity
Registration-based model reduction of parameterized PDEs with spatio-parameter adaptivity
Abstract: We present a nonlinear registration-based model reduction procedure for rapid and reliable solution of parameterized two-dimensional steady conservation laws. This class of problems is challenging for model reduction techniques due to the presence of nonlinear terms in the equations and also due to the presence of parameter-dependent sharp gradient regions that cannot be adequately represented […]

Sound sources in premixed flames
Sound sources in premixed flames
Abstract: Lean premixed combustion is the desired combustion regime in industrial gas turbines. It results in a low level of NOX emissions due to operating at lower temperatures and facilitates better combustion efficiency. However, the main issue with operating gas turbines in this regime is thermoacoustic instability, commonly initiated by combustion-generated sound. This issue is […]
