The spatial instability of inward radial Rayleigh–Bénard–Poiseuille flow was investigated using direct numerical simulations with random and controlled inflow forcing. were carried out a higher-order-accurate compact finite difference code in cylindrical coordinates. Inward flows can be found, for example, the collectors solar chimney power plants. conditions present chosen such that both stead...

Recent progress in fabricating high-quality conductors with small densities of defects has initiated studies a viscous electron fluid and motivated the search for evidence hydrodynamic regime transport. In this Letter we come up spin imaging technique, which can allow to attest emergence flows. Using numerical calculations, examine specific inhomogeneous distributions density injected sample Po...
