Dear Foamers,

Recently I am trying to understand how the momentum equations in Rotating Frame is developed, and I found the wiki page at:
http://www.openfoamwiki.net/index.ph...RF_development
which show the development for the eqns in MRF.

But I didnot understand some items in these eqns (cause pics can not be paste on this page, the questions in attached as doc format), can anyone help me to explain it? It will be appreciated!

These items include "nabla dot [omega crossmultiply r]" equal to zero?
