In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple
with acoustic pressure oscillations. If the heat release is sufficiently in phase with the …

Through triglobal resolvent analysis, we reveal the effects of wing tip and sweep angle on
laminar separated wakes over swept wings. For the present study, we consider wings with …

We reveal the effects of sweep on the wake dynamics around NACA 0015 wings at high
angles of attack using direct numerical simulations and resolvent analysis. The influence of …

This study analyses the interplay between classical acoustic modes and intrinsic
thermoacoustic (ITA) modes in a simple thermoacoustic system. The analysis is performed …

The response to forcing of a 2D laminar premixed slot flame is investigated by means of
linear analysis, based on the compressible flow equations with a two-step reaction scheme …

This study investigates the linear stability of a laminar premixed flame, anchored on a
square cylinder and confined inside a channel. Many modern linear analysis concepts have …

Gradient-based optimization algorithms, where gradient information is extracted using
adjoint equations, are efficient but can quickly slow down when applied to unsteady and …

An adjoint-based framework is presented that measures exact sensitivity from high-fidelity
simulations of turbulent reacting flows. The framework leverages and extends state-of-the-art …

Resolvent analysis is a powerful tool that can reveal the linear amplification mechanisms
between the forcing inputs and the response outputs about a base flow. These mechanisms …

Jets in crossflow are a recurring flow configuration in many engineering applications and
have been the subject of many computational and experimental investigations. While these …
