Wedge Geometry for Ultrasonic Delay Lines [PDF]
Compact ultrasonic delay lines using vitreous silica plates cut in the form of a wedge are described. Shear waves at frequencies in the 10–50 mc/sec range are reflected back and forth between the wedge surfaces, with resulting open beam paths at the sending and receiving transducers, and gradually overlapping paths at the small end of the wedge.

NON-TRADITIONAL GEOMETRY FOR WEDGE-SPLITTING TEST
The wedge-splitting test is widely used in the testing of fracture mechanical parameters of concrete or concrete-like materials. This test provides a stable crack propagation, which was analysed on a cube specimen. Another interesting application for measuring fracture mechanical properties combines wedge-splitting test with a three-point bending test.

Numerical simulation of heat transport mechanism in chemically influenced ternary hybrid nanofluid flow over a wedge geometry [PDF]
Ternary hybrid nanofluid flow over a wedge surface facilitates optimization, promotes industrial processes such as heat transfer, temperature regulation, material compatibility, energy efficiency and is very useful in equipment design.

Statics and dynamics of liquid barrels in wedge geometries [PDF]
We present a theoretical study of the statics and dynamics of a partially wetting liquid droplet, of equilibrium contact angle $\unicode[STIX]{x1D703}_{e}$, confined in a solid wedge geometry of opening angle $\unicode[STIX]{x1D6FD}$. We focus on a mostly non-wetting regime, given by the condition $\unicode[STIX]{x1D703}_{e}-\unicode[STIX]{x1D6FD}> ...

Straight wedge absorber geometry optimization for normal and oblique incidence [PDF]
—This paper presents a topology for improving the performance of straight wedge absorbing materials at oblique angles of incidence. The optimization process is based on a genetic algorithm and allows one to obtain a low reflection coefficient within a wide band of frequencies.

Image method solutions for free-particle wave packets in wedge geometries [PDF]
Using analogues of familiar image methods in electrostatics and optics, we show how to construct closed-form wave packet solutions of the two-dimensional free-particle Schrodinger equation in geometries restricted by two infinite wall barriers separated by an angle ΘN = π/N.

The Sensitivity of Salt Wedge Estuaries to Channel Geometry
AbstractThe authors develop a two-layer hydraulic model to determine the saline intrusion length in sloped and converging salt wedge estuaries. They find that the nondimensional intrusion length = CiL/hS depends significantly on the channel bottom slope and the rate and magnitude of landward width convergence, in addition to the freshwater Froude ...
