CFD Algorithms for Hydraulic Engineering Foreword
Foreword
After finishing my CFD Class Notes (Olsen, 1999), I realized there were a number of
topics not included in this basic text. Although there exist a number of books on CFD
modelling, I thought it would be practical to have a book with a detailed and hopefully
simple description of the more advanced topics for CFD in Hydraulic Engineering. It
would provide a general insight into the workings of a CFD program as an advice to
both users and people making new programs. The book also gives some insight into
my research over the last years, and I hope it can give inspiration to further research
in this field. Finally, it provides documentation of many of the algorithms in my SSIIM
computer programs.
Unlike the CFD Class Notes, the present text is only focused on the finite volume meth-
od. I have included details of topics I think is relevant for hydraulic engineering. This
applies especially to grid generation, roughness modelling and sediment transport.
I want to thank Prof. Morten Melaaen for his kind assistance and cooperation over the
last ten years. I have relied heavily on his doctoral thesis in Chapter 4. I also want to
thank Koen Blanchaert on assistance in collecting information for Chapter , bed
load transport on a transverse sloping bed.
Examples where the algorithms have been used are numerous, but I have only pre-
sented a limited number in this text. The reader is referred to the list of literature at the
end, the CFD Class Notes (Olsen, 1999) or one of the several web pages on CFD in
hydraulic engineering, for example /~nilsol/cfd
