What is the meaning of turbulence in physics?

What is the meaning of turbulence in physics?

Turbulence, In fluid mechanics, a flow condition (see turbulent flow) in which local speed and pressure change unpredictably as an average flow is maintained. Common examples are wind and water swirling around obstructions, or fast flow (Reynolds number greater than 2,100) of any sort.

What is the turbulence meaning?

: the quality or state of being turbulent: such as. a : great commotion or agitation emotional turbulence. b : irregular atmospheric motion especially when characterized by up-and-down currents.

Do we understand turbulence?

Turbulence is all around us, yet it’s usually invisible. Simply wave your hand in front of your face, and you have created incalculably complex motions in the air, even if you can’t see it. Motions of fluids are usually hidden to the senses except at the interface between fluids that have different optical properties.

What’s the difference between turbulent and turbulence?

turbulent flow is a flow which is characterized by chaotic changes in pressure and flow velocity. it is in contrast with laminar flow. Turbulence is unsteady movement of air or water, or of some other fluid where as stability is the field which analyses the stableness and the onset of instability of fluid flows.

Why is turbulence so important?

The mixing action of the turbulent flow enhances the temperature averaging effect in addition to the transfer of energy from the hot water to the surrounding fluid. When a hot object is cooled, the mixing action of turbulent flows in the fluid surrounding the object plays an important role in cooling it (Figure 2.3).

How do you stop turbulence?

Turbulence reduction by using anti-turbulence screens and honeycomb. Significant devices for turbulence reduction in wind tunnels are screens. Screens are employed to even the velocity variation of flow out of the settling section. They can remove fine vortex structures and honeycombs can remove large vortex structures …

Why does turbulence happen?

Turbulence is caused when an airplane flies through waves of air that are irregular or violent, which cause the aircraft to bounce around yawing, pitching, or rolling. You can compare turbulence to two oceans meeting.

What does Bulence mean?

Bülent is a Turkish masculine given name and a family name meaning “tall” and “high”, from Persian boland (Persian: بلند‎) which means tall or high.

Why is turbulent blood flow bad?

Risk factors that increase turbulence, such as plaque build-up or hardening of the arterial walls, serve to increase vascular resistance (sometimes referred to as SVR or systemic vascular resistance) and result in increased blood pressure, reduced blood flow, and an increased workload for the heart.

What is the problem with turbulence?

This is hard because of turbulence, a problem that gives physicists and mathematicians more trouble than you might think. On the physical side, turbulence happens when a smooth fluid flow starts to split into smaller eddies and vortices.

What is the most common cause of blood flow turbulence?

Therefore, high velocities and low blood viscosity (as occurs with anemia due to reduced hematocrit) are more likely to cause turbulence.

What is an example sentence for turbulence?

What does clear-air turbulence mean?

Clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet. Oct 4 2019
