Part A of this thesis by K. S. Brunner is titled "Two-Phase Flow Regime Transitions Under a D.C. Electric Field" and has the following link on MacSphere: < http://hdl.handle.net/11375/16329 > This report is Part B. / The PUMPANC subroutine in the FIREBIRD-III thermal hydraulic computer code models pump behaviour. The accuracy of this model is examined on the basis of available pump tests. Single phase test results on the Gentilly-2 primary heat transport pumps are compared to FIREBIRD-III predictions. As well, various two-phase pump tests are examined for the applicability of scaling small pump results to large pump results. Further areas of investigation are outlined. / Thesis / Master of Engineering (MEngr)
