Turbulent Flow

Turbulent Flow

Turbulent flow is characterized by unpredictable fluctuations in velocity and pressure, which result in a chaotic fluid movement distinct from the orderly patterns of laminar flow. While laminar flow is governed by smooth, parallel layers with minimal mixing, turbulent flow exhibits highly irregular, three-dimensional patterns. This behavior arises due to instabilities in the fluid's velocity profile, and amplifies as the flow velocity increases. Minor disturbances, known as turbulent spots,...

$Interference and Diffraction$ 02:18

Interference and Diffraction

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Phase Transitions

Phase Transitions

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to occupy...

Phase Transitions

Phase Transitions

A phase transition is the process in which a substance changes from one state of matter to another, like from a solid to a liquid, liquid to gas, or vice versa, at a specific temperature and under given pressure conditions. This change is spontaneous and is affected by alterations in temperature and pressure. These parameters impact the strength of the forces between molecules (intermolecular forces) in the substance.During a phase transition, both the initial and final phases of the substance...

Laminar and Turbulent Flow

Laminar and Turbulent Flow

Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the streamlines...

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...

Summary

This summary is machine-generated.

This study shows that pumping a system with an instability term, not random force, drives turbulence towards order. Inverse cascade turbulence is nonuniversal, depending on the forcing

Area of Science:

Quantum turbulence
Condensate dynamics
Statistical physics

Background:

Turbulence in superfluids and Bose-Einstein condensates exhibits unique phenomena.
The Gross-Pitaevskii model describes Bose-Einstein condensates.
Inverse cascades transfer energy to larger scales, unlike direct cascades in classical turbulence.

Purpose of the Study:

To investigate the formation of a coherent condensate via inverse cascade turbulence.
To analyze the spontaneous breakdown of statistical symmetries during condensate growth.
To determine the influence of forcing type on turbulence and phase transitions.

Main Methods:

Numerical simulations within the Gross-Pitaevskii model.
Analysis of statistical symmetries and phase transitions.
Description of anisotropic flux flows in k-space.

Main Results:

An inverse cascade creates a coherent condensate from small-scale turbulence.
Condensate growth breaks statistical symmetries: isotropy, then twofold, threefold, and fourfold.
Anisotropic flux flows emerge in k-space.
A hexatic phase with short-range positional and long-range orientational order is observed.
Phase transitions occur with instability forcing, but not with random forcing.

Conclusions:

System pumping with instability drives turbulence towards increased order.
Nonuniversality of inverse-cascade turbulence is demonstrated concerning the nature of small-scale forcing.
The type of forcing dictates whether phase transitions and ordering occur.
