Adiabatic waves along interfacial layers near the critical point
Near the critical point, isothermal interfacial zones are investigated starting from a non-local density of energy. From the equations of motion of thermocapillary fluids [1], we point out a new kind of adiabatic waves propagating along the interfacial layers. The waves are associated with the second derivatives of densities and propagate with a celerity depending on the proximity of the critic...
متن کاملCoupled wedge waves.
The interface between two wedges can be treated as a displacement discontinuity characterized by elastic stiffnesses. By representing the boundary between the two quarter-spaces as a displacement discontinuity, coupled wedge waves were determined theoretically to be dispersive and to depend on the specific stiffness of the non-welded contact between the two wedges. Laboratory experiments on iso...
متن کاملWaves on unsteady currents
Models for surface gravity wave propagation in the presence of currents often assume the current field to be quasi-stationary, which implies that the absolute wave frequency is time invariant. However, in the presence of unsteady currents or time-varying water depth, linear wave theory predicts a time variation of the absolute wave frequency and wavenumber . Herein, observations of wave frequen...
متن کاملSteady and unsteady nonlinear internal waves incident on an interface
Steady nonlinear internal waves are commonly described by the Dubreil-JacotinLong equation. This equation contains unknown functions of the stream function, representing the density and vorticity fields. Often these are determined by upstream conditions where the flow is assumed to be known. But for the case when the waves are periodic in the horizontal direction, these functions need to be det...
متن کاملThe Pattern of Caspian Sea Water Penetration Into Anzali Wetland: Introduction of a Salt Wedge
Measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of Caspian Sea penetration into Anzali Wetland was determined. The results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. A pattern of saltwater and freshwater interface is presen...
