This investigation considers the effect of axial pressure gradient on the dynamics of flame–
vortex interaction for a lean premixed bluff body stabilized flame. Large eddy simulations …

The linear eigenmode characterizations and the nonlinear turbulence energy spreading of
the drift waves in a tokamak plasma with strong pedestal gradient are numerically …

This work investigates the spatio-temporal evolution of coherentstructures in the wake of a
generic high-speed train. Spectral properorthogonal decomposition is used to extract energy …

Large eddy simulation data of a bluff-body stabilized flame are analyzed using spectral
proper orthogonal decomposition (SPOD) to investigate:(i) the role of flame-vortex …

Abstract In this study, the 0-1 test method is combined with the maximum Lyapunov index to
analyze the influence of pellet length (10, 15, 20 mm) and combustion air supply (60, 90 …

We investigate self-excited axisymmetric oscillations of a lean premixed methane--air V-
flame in a laminar annular jet. The flame is anchored near the rim of the centrebody, forming …

The present study makes use of the adjoint modes of the Linearized Reactive Flow (LRF)
equations to investigate the Intrinsic Thermoacoustic (ITA) feedback loop of a laminar …

Large eddy simulation data of a bluff-body stabilized flame are analyzed using spectral
proper orthogonal decomposition (SPOD) to investigate:(i) the role of flame-vortex …

Adopting an engine igniter with high efficiency and ignition performance is essential for
reliable operation of liquid rocket engines. In this study, we developed a spark torch igniter …

The thesis aims to apply recent developments of methodology from the field of linear
instability theory to the study of combustion instability. The flame instability here refers to the …
