# Speed of fluid in a turbulent flow

• Domenico94
In summary, the fluid speed and density change when passing from laminar flow to turbulent flow, depending on the Mach number. The velocity and density of a single fluid element may change as it passes from the front to the back of an object, while a turbulent wake differs from a laminar wake. In this case, the difference between a turbulent wake past an object and a laminar wake before the object can be seen with a Mach number of 0.2.

Suppose a fluid passes from having laminar flow, to having a turbulent flow (like when passing after an object). How do fluid speed and fluid density change after that?

The density answer depends on the Mach number of the flow. For velocity, I'm not quite sure what you're asking. Do you mean to ask how the velocity and density of a single fluid element change as it passes from the front to the back of an object? Or do you mean to ask how a turbulent wake differs from a laminar wake?

I was asking for how a turbulent wake ( past an object) differs from a laminar wake( before object) for a mach number of 0.2

A wake is, by definition, downstream (behind) the object.

## 1. What is the speed of fluid in a turbulent flow?

The speed of fluid in a turbulent flow can vary greatly, ranging from slow to very fast. The average speed of a turbulent flow is typically faster than a laminar flow, but it can also have areas of very high speed and areas of slower speed.

## 2. How is the speed of fluid in a turbulent flow measured?

The speed of fluid in a turbulent flow is typically measured using a device called a hot wire anemometer. This instrument measures the speed of the fluid by measuring the change in temperature caused by the fluid's movement.

## 3. What factors affect the speed of fluid in a turbulent flow?

The speed of fluid in a turbulent flow is affected by several factors, including the viscosity of the fluid, the size and shape of the object the fluid is flowing around, and the velocity and direction of the flow.

## 4. How does the speed of fluid in a turbulent flow impact its behavior?

The speed of fluid in a turbulent flow can greatly impact its behavior. At high speeds, the flow can become more chaotic and unpredictable, making it difficult to control. It can also cause more mixing and blending of different fluids, which can be advantageous in certain applications.

## 5. Can the speed of fluid in a turbulent flow be controlled?

Yes, the speed of fluid in a turbulent flow can be controlled through various methods such as using flow regulators or turbulence-reducing devices. However, complete control of turbulent flow can be challenging and is an ongoing area of research for scientists and engineers.
