Journal ArticleDOI
A preconditioned Navier–Stokes method for two-phase flows with application to cavitation prediction
Robert F. Kunz,David A. Boger,David R. Stinebring,Thomas S. Chyczewski,Jules W. Lindau,Howard J. Gibeling,Sankaran Venkateswaran,T. R. Govindan +7 more
TL;DR: In this paper, an implicit algorithm for the computation of viscous two-phase flows is presented, which employs a dual-time, preconditioned, three-dimensional algorithm, with multi-block and parallel execution capabilities.

Mark W. Mcbride,David A. Boger,Robert L. Campbell,Gregory P. Dillon,Stephen A. Hambric,Robert F. Kunz,Boris Leschinsky,Thomas M. Mallison,James Runt,Justin M. Walsh +9 more
TL;DR: An impeller is a part of a pump for pumping fluids, such as blood, and may include a cannula having a proximal portion with a fixed diameter, and a distal portion with an expandable diameter.
Multi-phase CFD analysis of natural and ventilated cavitation about submerged bodies
Robert F. Kunz,David R. Stinebring,Thomas S. Chyczewski,David A. Boger,Howard J. Gibeling,T. R. Govindan +5 more
TL;DR: In this article, a multiphase Navier-Stokes algorithm is used to model the flow about submerged bodies subject to natural and ventilated cavitation. But the model is not suitable for the case of large numbers of bodies and it cannot handle the presence of condensable and non-condensable gas fields.
Journal ArticleDOI
Performance Analysis of Cavitating Flow in Centrifugal Pumps Using Multiphase CFD
Richard B. Medvitz,Robert F. Kunz,David A. Boger,Jules W. Lindau,Adam M. Yocum,Laura L. Pauley +5 more
TL;DR: In this article, a multi-phase CFD method is used to analyze centrifugal pump performance under developed cavitating conditions, wherein mixture momentum and volume continuity equations are solved along with vapor volume fraction continuity.
Patent
Expandable impeller pump

TL;DR: An impeller includes a hub, and a plurality of blades supported by the hub, the blades being arranged in at least two blade rows as discussed by the authors, and the impeller may also have an operational configuration in which at least some of the blades are deformed from the deployed configuration upon rotation of the impellers.
