Hydrodynamic stability, an important branch of fluid mechanics, owes its popularity to the successful prediction of the transition of (unstable) laminar states in a wide class of flows. While the traditional approach has ...

A granular material is a collection of solid particles or grains such that most of the particles are in contact with at least some of their neighboring particles. The terms granular materials, bulk solids, particulate ...

The galactic cosmic rays (GCR) are charged particles, primarily protons and helium nuclei. In the present work, by applying data analysis techniques, we have investigated the proposal that GCR can in uence precipitation. ...

The main objective of this thesis is to study the instability and evaluate the likely mechanisms of transition to turbulence in divergent and small-scale (as discussed below) pipe flows. It was first demonstrated by ...
