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?
