Feng et al. Leutwyler and Dalton [ To read about the book is just not enough! I would also like to thank Dr. Chapter 1 will contain a literature review regarding the research done on butterfly valves. It should also be noted that this pressure loss represents a gross measurement instead of net measurement. Spall deserves my gratitude and respect for being an exceptional professor and mentor to me throughout my studies here at Utah State University.

Huang also compared his numerical results with the experiments carried out by Blevins [9]. The master thesis opportunities germany was installed in the seated downstream position in a A mesh of nearly one million cells was used with a domain extending eight pipe diameters upstream from the valve and approxi- mately ten pipe diameters downstream.
