Fox J.A. Transient Flow In Pipes, Open Channels And Sewers

1989. , 284 pagesThis coverage of unsteady flow in pipes and channels show how to build mathematical models of such flows and can be used as a basis of computer programs for the solution of such problems. It will be of value to a wide range of industries as well as to students of specialist courses and bio-engineers in research organizations.The book extends the coverage of unsteady flow provided in the author's previous book on the subject. In particular, open channel unsteady flows are dealt with in more detail, with descriptions of both two-dimensional and three dimensional approaches. Unsteady pump and turbine behaviours are also described and methods of analysing them are given, together with a new method of resonance prediction.In the final chapter Fortran sub-routines are given which can be used as the basis of a computer program developed by the reader. These are presented in Fortran IV, which is the most widely distributed language in the world.Nomenclature
