Question on PISO algorithm in computation fluid dynamics book by Chung

Hi,

Can someone please tell me why in the predictor equation 6.3.21 and even 5.3.16 of the computational fluid dynamics book by Chung (2nd edition) , the pressure term is evaluation an the the 'n' time step and where does the term at the beginning of equation 6.3.21 come from?

Thanks a lot.

It's google link is:

http://books.google.co.uk/books?id=C...hanics&f=false

but the pages I'm after are not available. I think I would have to upload more pages than just the pages where the equations are. I guess my question goes to those who have access to the book.

I now know why pressure is evaluated an the the 'n' time step, just need to know where the term at the beginning of equation 6.3.21 comes from?
