Derivation of "stokeslet"

[KRP]

Ok, so basically I cannot find ANYWHERE the step-by-step derivation of the free-space Green's function for the velocity field generated by a point force in a fluid (the Stokeslet).


I have not for the life of my got a clue why it somehow turns into a tensor along the way...?

help appreciated.

This thread got no love in the Homework Forum. Maybe it will have better luck here in Engineering.

Hey KRP,

Try these articles. I don't think they have EXACTLY the information you need but might be able to lead you to it - a couple mention other methods, etc.. I tried to upload the pdf's for these but the limit is 50kB. If you're interested in giving them a look, you can try to obtain them from Science Direct OR I can email them to you. I'll try to check back to see what you want to do.

Hope it helps
