Abstract: Linear analysis of gravitational instabilities in the presence of a shear layer and shear instabilities in the presence of a free surface is performed. This study is relevant to shallow mixing layers, such as flow in ...

Abstract: This paper performs linear stability analysis of base flow velocity profiles for laminar and turbulent water-hammer flows. These base flow velocity profiles are determined analytically, where the transient is generated by ...

Abstract: A linear stability analysis of lateral motions in shallow flow open channels with a free surface is presented. Unlike previous studies, this work does not employ the rigid-lid assumption. Computations revealed that the ...

Abstract: In a recent paper, an elegant, efficient, and easy to apply transient-based leakage detection method was proposed. The method exploits the fact that friction and leakage damp the modes of transient waves in a different ...
