Hydraulic jump in triangular channel
Journal of Hydraulic Research, 1987The hydraulic jump in the triangular channel is analysed using an elementary approach. The results regarding the sequent depth ratio are confirmed by model observations. Furthermore, the length characteristics, the surface profiles and typical velocity distributions are discussed.

A triangular shaped channel MIM waveguide filter
Journal of Modern Optics, 2012A compact plasmonic branch-shaped metal–insulator–metal (MIM) waveguide with a triangular-annular channel is proposed and investigated. The results show that all-band waves can transmit through the structure when it has transmission symmetry. As the symmetry is broken, a typical filtering function is obtained and the transmissivity of the resonance ...

Resistance Experiments in a Triangular Channel
Journal of the Hydraulics Division, 1959400-ft adjustable-slope triangular flume was tested smooth and also roughened with small rectangular battens at various spacings; comparison is made of Manning’s formula with some more recent suggestions and velocity distribution, secondary currents, and other phenomena are reported.

Hydraulic jump in a sloped triangular channel
Canadian Journal of Civil Engineering, 2009The hydraulic jump in a sloped triangular channel of 90° central angle is theoretically and experimentally examined. The study aims to determine the effect of the channel's slope on the sequent depth ratio of the jump. A theoretical relation is proposed for the inflow Froude number as function of the sequent depth ratio and the channel slope.

Side Weir in Triangular Channel
Journal of Irrigation and Drainage Engineering, 1992In this study, numerical investigations of flow over side weirs in triangular channels are reported. Numerical models are obtained from energy principles and solved by a finite difference method. The resutls are presented in graphical form. The study covers sub- and supercritical flow regimes.

Simple haptotactic gradient generation within a triangular microfluidic channel
Lab on a Chip, 2010Most microfluidic devices developed to date for the analysis of live cells incorporate channels with relatively simple constant rectangular or semi-circular cross-sections, relying on complex channel network geometries rather than alteration of the shapes of the channels themselves for development of diverse functional fluidic controls, e.g., spatial ...

Drag Reduction in a 90° Triangular Open Channel
Journal of Rheology, 1980Drag reduction with polymer additives was measured in a 90° triangular open channel. Also, the laser Doppler technique was employed to measure the velocity profiles in the same flow system. The amount of drag reduction depended on both Reynolds number and polymer concentration in almost the same manner as obtained in a turbulent pipe flow. In addition,

Seepage from an Array of Triangular Channels
Journal of the Engineering Mechanics Division, 1967The problem of seepage losses from a system of parallel triangular channels is solved exactly by use of conformal mapping. Formulas for the discharge and the shape of the free surface are given. In general, the system is underlain by a drainage layer at a finite depth, and the case of an infinitely deep aquifer is solved separately.

Superplastic Forming of Triangular Channels with Sharp Radii
Journal of Materials Engineering and Performance, 2014The superplastic forming process is used to form light weight components with complex features in one manufacturing step. However, the non-uniformity of the produced part thickness and the possibility of severe thinning are among its major disadvantages. The goal of this parametric study was to investigate feasible geometries for triangular channels to
