This paper presents recent progress in the field of thermoacoustic combustion instabilities in
propulsion engines such as rockets or gas turbines. Combustion instabilities have been …

The two-phase mixing layer formed between parallel gas and liquid streams is an important
fundamental problem in turbulent multiphase flows. The problem is relevant to many …

This article investigates the appearance of instabilities in two planar coflowing fluid sheets
with different densities and viscosities via experiments, numerical simulation and linear …

Six flow modes are distinguished in the flow-focusing experiments of a liquid jet forced by a
high-speed air stream. The domains of the modes are identified on the parameter space of …

Understanding the development and breakup of interfacial waves in a two-phase mixing
layer between the gas and liquid streams is paramount to atomization. Due to the velocity …

Two-dimensional (2D) and three-dimensional (3D) instabilities in the wake of a circular
cylinder placed near to a moving wall are investigated using direct numerical simulation …

Traditional stability tools have done much in the last few decades to demonstrate the
significance of modal instabilities as a pathway for laminar to turbulent transition in …

In this article we propose a stochastic bed load transport formulation within the framework of
the frictional shallow-water equations in which the sediment transport rate results from the …

The shear instability occurring at the interface between a slow water layer and a fast air
stream is a complex phenomenon driven by momentum and viscosity differences across the …

In the framework of linear stability theory, we analyze how a liquid-gas mixing layer is
affected by several parameters: viscosity ratio, density ratio, and several length scales …
