Uniform Depth Channel Flow

Uniform Depth Channel Flow

Uniform depth channel flow keeps fluid depth consistent along channels such as irrigation canals. In natural channels, such as rivers, approximate uniform flow is often assumed. This condition occurs when the channel’s bottom slope matches the energy slope, balancing potential energy lost from gravity with head loss due to shear stress. This balance prevents depth changes along the channel length, resulting in a steady, uniform flow.Uniform flow in open channels with a constant cross-section...

Uniform Depth Channel Flow: Problem Solving

Uniform Depth Channel Flow: Problem Solving

To calculate the flow rate for a trapezoidal channel, first, identify the bottom width, side slope, and flow depth of the channel. The cross-sectional area (A) corresponding to the depth of flow (y), channel bottom width (B), and side slope (θ) is determined by:Next, calculate the wetted perimeter, which includes the bottom width and the sloped side lengths in contact with the water. Using the values of the cross-sectional area and the wetted perimeter, determine the hydraulic radius by...

Standing Waves in a Cavity

Standing Waves in a Cavity

A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Propagation of Waves

Propagation of Waves

When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

Background:

Underwater wireless optical communication (UWOC) systems face challenges from scattering and absorption, limiting performance.
Maintaining stable, high-bandwidth communication underwater is crucial for various applications, including remote sensing and exploration.
Existing UWOC systems often struggle with environmental disturbances like bubbles, which cause signal fading.

Purpose of the Study:

To demonstrate a novel single-source, full-duplex UWOC system.
To leverage digital micromirror device (DMD) technology for generating Bessel beams for improved UWOC performance.
To investigate the system's resilience to bubble-induced disturbances.

Main Methods:

A digital micromirror device (DMD) was used to generate Bessel-like beams via Fourier transformation of a ring-shaped pattern.
A MEMS grating modulator facilitated retro-reflective uplink transmission over the same optical path.
System performance was evaluated under simulated bubble-disturbed underwater conditions.

Main Results:

The Bessel-beam based UWOC system successfully achieved full-duplex communication.
The system demonstrated enhanced resistance to intensity fading caused by bubbles compared to Gaussian beams.
Proof-of-concept uplink transmission was achieved even under bubble-disturbed conditions.

Conclusions:

DMD-based Bessel beam generation offers a compact and robust solution for full-duplex UWOC.
The inherent properties of Bessel-like beams significantly improve resilience to localized perturbations like bubbles.
This technology paves the way for more reliable underwater optical communication systems.
