SUMMARY

The convective time of a flow can be calculated using the Reynolds number (Re) by dividing the characteristic length of the system by the mean flow velocity. This relationship is application-specific, meaning that the exact formula may vary depending on the context of the flow being analyzed. Understanding the Reynolds number is crucial for accurately determining convective time in fluid dynamics.

PREREQUISITES
  • Understanding of Reynolds number and its significance in fluid dynamics
  • Knowledge of characteristic length in flow systems
  • Familiarity with mean flow velocity concepts
  • Basic principles of convective heat transfer
NEXT STEPS
  • Research the application of Reynolds number in various fluid dynamics scenarios
  • Explore the relationship between characteristic length and flow velocity
  • Learn about convective heat transfer equations and their derivations
  • Investigate case studies involving convective time calculations in engineering applications
USEFUL FOR

Engineers, fluid dynamics researchers, and students studying thermodynamics or heat transfer who seek to understand the relationship between Reynolds number and convective time in flow systems.

How does one determine (also read as "what is") the convective time of a flow given its Reynolds number? I've not been able to find a proper description via Google and am thinking it may be too "application specific." Regardless, if anyone has knowledge of this I would greatly appreciate your insight!

It is application specific, but it is often the characteristic length of your system (used for Re) divided by the mean flow.
 
Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
