Potential Flow Theory Introduction (Essentials of Fluid Mechanics)

Показать описание

This video explains the most important ideas of potential flow theory. Without these it is impossible to understand potential flows. The key ideas are

- Potential flows are always irrotaional
- When a PF is incompressible you get laplace's eqn
- You can combine potential flows

EXCELLENT and GREAT video. I wish I had this CLEAR and SIMPLE explanation to this complex subject of fluid mechanics in my past university years as a M.E. student. Thank you! And keep up your great work.

You should link the next portions of this video to the comments below! Nice explanation; this can be used to establish the assumptions for Transport Phenomena and Fluid Mechanics courses during exams.

Well explain. Super clear! This video is underrated

Thank You ! I can't believe it is this hard to find an explanaiton of what velocity potential is

Your Explanation is so easy that i decided to solve Navier Stokes Equations 😂.

how do they get the simple flow stream function? any derivation might help

MrDemonhell

Nice presentation of the potential flow

I don't think you showed that it is incompressible--only that it is equal to the laplace equation.
I think it's because the Potential Flow comes from a complex analytic function (which means real & imaginary parts are harmonic), thus establishing the 0 equality

Pls what's the best textbook for this topic

nice vid! short, to the point and easy to get understand.

if a flow is ideal, there is no friction. Hence, the net torque on an object is zero. torque = integral(v.dr). This quantity is zero if and only if v is gradient of a velocity potential so v = del(phi). In real case, for instance, for fully developed flow this is not possible. You cannot get a fully develop flow from gradient of any scalar. You can try yourself.

what is difference between ideal and potential flow why give ddifferent name please give reply with reasons

neerajmishra

what is that scalar function "fi"

simhadivya

the richard Feynman hates them got me 😂😂😂😂

He never said what a potential flow is!!!
