Total pressure etc.

Maxim Olshanskii

Dear CFD experts,

The question is a bit from mechanics:

The term (u.grad)u + grad p in momentum equation has a clear meaning of convection and gradient of kinimatic pressure.

This term can be rewritten as (curl u)x(u) + grad P, where P is now Bernoulli (or total) pressure, an invariant in Euler limit.

I wounder of any interpretation for (curl u)x(u) term from the standpoint of physics/mechanics?! x - stands for vector product.

Thank you much for any suggestions and/or references!
