The flexible shape Palmer-Bowlus flume is a simple device for flow measurement in free-surface flow circular channels and conduits. In this study, the discharge-stage relation for Palmer-Bo...

We examine the convective stability of hydrodynamic discs with full stratification in the local approximation and in the presence of thermal diffusion (or relaxation). Various branches of the relevant axisymmetric dispersion relation derived by Urpin

In this paper, D-Wave quantum computing Ising model is employed and evaluated for the forecasting of positive extremes of daily mean air temperature. Forecast models are designed with two to five qubits, which represent 2-, 3-, 4-, and 5-day historic

We consider the evolution of linear non-axisymmetric perturbations in discs with radially and vertically stratified equilibria. We work in the shearing sheet and Boussinesq approximations. We choose density and pressure equilibrium fields compatible

Because of its non-Hermitian property, the stability analysis of a shear-flow system is rather complex. While the Kelvin–Helmholtz instability, being a spatially global and temporally exponential mode, can be detected by a standard analysis of eige

The structure of Kelvin's method, which is driving great advances in the study of shear-flow systems, has been carefully re-examined. It is shown that this method is a particular case of a generalized modal approach. The generality of Kelvin's soluti

Transient and secular behaviors of interchange fluctuations are analyzed in an ambient shear flow by invoking Kelvin’s method of shearing modes. Because of its non-Hermitian property, complex transient phenomena can occur in a shear flow system. Th

The stabilizing effect of a shear flow on a current-driven instability has been studied by means of Kelvin’s representation of spatially-inhomogeneous Galilean transform. Even though conspicuous transient growth may occur, the mixing effect of the

Discs with a rotation profile depending on radius and height are subject to an axisymmetric linear instability, the vertical shear instability. Here we show that non-axisymmetric perturbations, while eventually stabilized, can sustain huge exponentia
