Speed of fluid in a turbulent flow

AI Thread Summary
In turbulent flow, fluid speed and density can change significantly as the flow transitions from laminar to turbulent, particularly around objects. The Mach number, such as 0.2 in this case, influences density changes in the fluid. The discussion clarifies that a turbulent wake, which occurs behind an object, differs from a laminar wake, which is present before the object. The specifics of how velocity and density change for a fluid element during this transition are crucial for understanding the dynamics of fluid behavior. Understanding these differences is essential for applications in fluid dynamics and engineering.

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.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
