The excitation of pressure fluctuations in a model jet-driven Helmholtz oscillator is experimentally investigated. An axisymmetric channel consisted of a cylindrical chamber with a nozzle in the front cover and an outlet opening in the back one. Opti

As fluids and gases move through porous media, they generate acoustic noise. It is shown that the shape of the noise spectra is determined by the properties of the fluid and the porous reservoir, as well as by the flow regime. Our study has experimen

Viscous fingering shaped as curvature of the fluid displacement fronts are usually formed in porous media and Hele-Shaw cell when a liquid with a high viscosity is displaced by a liquid with a lower viscosity. Such interfacial instability is undesira
