Experimental Study of a Cavitating Centrifugal Pump During Fast Startups http://link.aip.org/link/doi/10.1115/1.4000845 S. Duplaa, O. Coutier-Delgosha, A. Dazin, O. Roussette, G. Bois, and G. Caignaert<br/> The startup of rocket engine turbopumps is generally performed only in a few seconds. It implies that these pumps reach their nominal operating conditions after only a few rotations. During these first rotations of the blades, the flow evolution in the pump is governed by transient phenomena, based ... [J. Fluids Eng. 132, 021301 (2010)] published Thu Jan 28, 2010. On the Relationships Among Strouhal Number, Pressure Drag, and Separation Pressure for Blocked Bluff-Body Flow http://link.aip.org/link/doi/10.1115/1.4000575 W. W. H. Yeung<br/> Strouhal number, pressure drag, and separation pressure are some of the intrinsic parameters for investigating the flow around a bluff-body. An attempt is made to formulate a relationship involving these quantities for flow around a two-dimensional bluff section of various shapes in a confined envir ... [J.

Tijsseling, M. C. M. Rutten, and F. N. van de Vosse<br/> Research on wave propagation in liquid filled vessels is often motivated by the need to understand arterial blood flows. Theoretical and experimental investigation of the propagation of waves in flexible tubes has been studied by many researchers. The analytical one-dimensional frequency domain wave ... [J.

Comparison of Experiments and Simulation of Joule Heating in ac Electrokinetic Chips http://link.aip.org/link/doi/10.1115/1.4000740 Stuart J. Williams, Pramod Chamarthy, and Steven T. Wereley<br/> ac electrokinetic manipulations of particles and fluids are important techniques in the development of lab-on-a-chip technologies. Most of these systems involve planar micro-electrode geometries, generating high strength electric fields. When these fields are applied to a dielectric medium, Joule he ... [J.

Computational Investigation of a Race Car Wing With Vortex Generators in Ground Effect http://link.aip.org/link/doi/10.1115/1.4000741 Yuichi Kuya, Kenji Takeda, and Xin Zhang<br/> Vortex generators can be applied to control separation in flows with adverse pressure gradients, such as wings. In this paper, a study using three-dimensional steady computations for an inverted wing with vortex generators in ground effect is described. The main aim is to provide understanding of th ... [J.

Huyer, Amanda Dropkin, James Dick, and David Beal<br/> A computational study was performed to investigate a method to generate vehicle maneuvering forces from a propulsor alone. A ducted, preswirl propulsor was configured with an upstream stator row and downstream rotor. During normal operation, the upstream stator blades are all situated at the same pi ... [J.
