SUMMARY

The discussion centers on determining whether the flow described by the stream function psi = 4y - (y^3)/3 is fully developed. A flow is classified as fully developed when there is no change in the u component along the flow direction, specifically when du/dx = 0. The participants confirm that this condition is essential for establishing flow development status.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with stream functions in fluid mechanics
  • Knowledge of the concept of fully developed flow
  • Basic calculus, particularly differentiation
NEXT STEPS
  • Study the criteria for fully developed flow in fluid mechanics
  • Learn about stream functions and their applications in fluid dynamics
  • Explore the implications of the u component in flow analysis
  • Review calculus techniques for evaluating derivatives in physical contexts
USEFUL FOR

Students and professionals in fluid dynamics, mechanical engineers, and anyone studying flow characteristics in fluids.

Homework Statement



The following stream function holds for a certain flow of water at 20 C.
psi = 4y - (y^3)/3.

Is this flow fully developed?

Homework Equations



psi = 4y - (y^3)/3.

The Attempt at a Solution



How am i suppose to tell if a flow is fully developed or not from the stream function? Direct me to what should i study to find the answer.

I found the solution ..so here it is... for a flow to be fully developed, it should have no change in the u component. i.e. du/dx = 0
