A Linear Dynamic Analysis of Vent Condensation Stability - Brennen, C.
This paper presents a theoretical model whose purpose is to attempt to understand why these flows are unstable and to extract the important parameters and frequencies pertaining to the instability.

Stability of Hydraulic Systems with Focus on Cavitating Pumps - Brennen, C. E.; Braisted, D. M.
Increasing use is being made of transmission matrices to characterize unsteady flows in hydraulic system components and to analyze the stability of such systems.

Cavitation Bubble Dynamics and Noise Production - Brennen, Christopher E.
This paper presents a summary of some recent observations of the interaction between individual traveling cavitation bubbles and the nearly solid surface.
145.
Some Current Advances in Cavitation Research - Brennen, Christopher E.
Several recent experimental and analytical investigations of cavitating flows have revealed new phenomena which clearly affect how we should view cavitation growth and collapse and the strategies used to ameliorate its adverse effects.

Fluid Flow Equations for Rotordynamic Flows in Seals and Leakage Paths - Brennen, C. E.; Uy, R. V.
Fluid-induced rotordynamic forces produced by the fluid in an annular seal or in the leakage passage surrounding the shroud of a pump or turbine, are known to contribute substantially to the potential excitation forces acting on the rotor.

Fission of Collapsing Cavitation Bubbles - Brennen, Christopher E.
High-speed observations (for example, Lauterborn and Bolle 1975, Tomita and Shima 1990, Frost and Sturtevant 1986) clearly show that though a collapsing cavitation bubble approaches its minimum size as a coherent single volume, it usually reappears in the first rebounding frame as a cloud of much smaller bubbles or as a highly distorted single volume (see, for example, figure 2).

A Remarkable Example of Bubble Nucleation Suppression - Creech, J.; Divino, V.; Patterson, W.; Zalesky, P. J.; Brennen, C. E.
Suppression of cavitation is a relatively common goal of fluid engineers and therefore examples of bubble nucleation suppression in other technological contexts are useful in suggesting ways in which such suppression might be achieved.

Computer Simulation of Chute Flows of Granular Materials - Campbell, C. S.; Brennen, C. E.
The purpose of the present paper is to present results from computer simulations of the flow of granular materials down inclined chutes or channels and to compare the results of these calculations with existing experimental measurements of velocity, solid fraction and mass flow rate profiles.

A Brief Note on the Interaction of an Actuator Cascade with a Singularity - Chamieh, D.; Acosta, A. J.; Brennen, C. E.; Caughey, T. K.
We have recently become concerned with making estimates of steady forces that may be exerted between moving blade rows and stationary blade rows or volutes.

Experimental Measurements of Hydrodynamic Stiffness Matrices for a Centrifugal Pump Impeller - Chamieh, D. S.; Acosta, A. J.; Brennen, C. E.; Caughey, T. K.; Franz, R.
The objective of the Rotor Force Test Facility at the California Institute of Technology is to artificially orbit the center of rotation of an impeller enclosed within a volute over a range of frequencies from zero to synchronous and to measure the resulting forces on the impeller.

On the Acoustical Dynamics of Bubble Clouds - d'Agostino, L.; Brennen, C. E.
Recently, Morch [1,2,3,4] Chahine [5,6] and others have focused attention on the dynamics of a cloud or cluster of cavitating bubbles and have expanded on the work of van Wijngaarden [7,8] and others.

Rotordynamic Forces on Centrifugal Pump Impellers - Franz, R.; Arndt, N.; Caughey, T. K.; Brennen, C. E.; Acosta, A. J.
The asymmetric flow around an impeller in a volute exerts a force upon the impeller.

Granular State Effects on Wave Propagation - Hostler, Stephen R.; Brennen, Christopher E.
In the present paper, wave speeds and attenuation rates are first examined for a static granular bed for a variety of system parameters including particle size, composition and the overburden of the material above the measuring transducers.
