Reason for using delta u/v in momentum eqn?

Hi!
I have read some papers and they have expressed the velocity in terms of du/dv ie u(n+1)-u(n)=du. However others just used the absolute u/v. Is there any preferred advantage of using du/dv? Is it better in a steady case? Thank you |

Hi CH, I guess the delta-formulation arises from the attempt to linearize the NS-eqns by let's say Newton or Picard iterations.
Best, Chris |
