In this paper, we study the linear stability properties of perturbations around the
homogeneous Couette flow for a 2D isentropic compressible fluid in the domain T * RT× R …

This paper investigates the non-normal nature of premixed flame–acoustic interaction. The
thermoacoustic system is modelled using the acoustic equations for momentum and energy …

In this paper, we investigate linear stability properties of the 2D isentropic compressible
Euler equations linearized around a shear flow given by a monotone profile, close to the …

We present a unifying solution framework for the linearized compressible equations for two-
dimensional linearly sheared unbounded flows using the Lie symmetry analysis. The full set …

We analytically consider how velocity shear in the corona and solar wind can cause an
initial Alfvén wave to drive up other propagating signals. The process is similar to the familiar …

Aerodynamic sound generation in shear flows is investigated in the light of the breakthrough
in hydrodynamics stability theory in the 1990s, where generic phenomena of non-normal …

We revisit our earlier study of the evolution of an initial propagating Alfvén wave in a
magnetic-field-aligned flow with a cross-field velocity shear. Our goal is to show how the …

Thermoacoustic instabilities severely restrict the operating regimes and reduce the life of
gas turbines as they induce large amplitude pressure fluctuations. During instability …

The three-dimensional linearized optimal energy growth mechanism, in plane parallel shear
flows, is re-examined in terms of the role of vortex stretching and the interplay between the …

The aim of this paper is to substantiate the importance of non-normality of shear flow linear
operators and its consequence--the non-modal dynamics of the perturbations--in the …
