Speed of fluid in a turbulent flow

Click For Summary
SUMMARY

The discussion focuses on the transition of fluid speed and density as a fluid moves from laminar to turbulent flow, particularly in the context of a Mach number of 0.2. It clarifies that the density of the fluid is influenced by the Mach number, while the specifics of velocity changes depend on whether the inquiry pertains to a single fluid element or the overall characteristics of the turbulent wake compared to the laminar wake. The distinction between turbulent and laminar wakes is emphasized, with the turbulent wake occurring downstream of the object.

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.
