1. The dynamic behavior and compliance of a stream of cavitating bubbles - Brennen, C. Both quasistatic and more general linearized dynamic analyses are made of the perturbations to a cavitating flow through a region of reduced pressure in which the bubbles first grow and then collapse.
2. Cavity-flow wall effects and correction rules - Wu, T. Yao-Tsu; Whitney, Arthur K.; Brennen, Christopher This paper is intended to evaluate the wall effects in the pure-drag case of plane cavity flow past an arbitrary body held in a closed tunnel, and to establish an accurate correction rule.
4. Bow Wave Dynamics - Waniewski, T. A.; Brennen, C. E.; Raichlen, F. Experimental studies of air entrainment by breaking waves are essential for advancing the understanding of these flows and creating valid models.
6. Observation of Damage Growth in Compressively Loaded Laminates - Chai, H.; Knauss, W. G.; Babcock, C. D. An experimental program to determine tie phenomenological aspects of composite-panel failure under simultaneous compressive n-plane loading and low-velocity transverse impact [C-75 m/s (0-250 ft/s)] is described.
8. Impeller-Induced Rotor-Dynamic Forces - Acosta, Allan J.; Brennen, Christopher E.; Caughey, Thomas K. The flow through and around the rotor of a turbomachine exerts a force on the rotor and, hence, rotor shaft and bearing system.
10. Experiments on Chute Flows of Granular Materials - Ahn, H.; Brennen, C.E.; Sabersky, R. H. Experiments on continuous, steady flows of granular materials down an inclined channel or chute were made with the object of acquiring information on the rheological properties of the granular material flow and the nature of the boundary condition on the base of the channel.
11. Measurements of Velocity, Velocity Fluctuation, Density, and Stresses in Chute Flows of Granular Materials - Ahn, H.; Brennen, C. E.; Sabersky, R. H. Two neighboring fiber-optic displacement probes provide a means to measure (1) the mead velocity by cross-correlating two signals from the probes, (2) the unsteady or random component of the particle velocity in the longitudinal direction by a procedure of identifying particles, and (3) the mean particle spacing at the boundaries by counting the frequency of passage of the particles.
12. Analysis of the Fully Developed Chute Flow of Granular Materials - Ahn, Hojin; Brennen, Christopher E.; Sabersky, Rolf H. Existing constitutive relations and governing equations have been used to solve for fully developed chute flows of granular materials.
13. Rotor-Stator Interaction in a Diffuser Pump - Arndt, N.; Acosta, A. J.; Brennen, C. E.; Caughey, T. K. Steady and unsteady pressure measurements were taken on the diffuser vanes, and the shroud wall of a vaned and a vaneless diffuser.
15. Observations on Off-Design Flows in Non-Cavitating Axial Flow Inducers - Bhattacharyya, Abhijit; Acosta, Allan J.; Brennen, Christopher E.; Caughey, Thomas K. This paper describes an investigation of the flows in unshrouded and shrouded inducers which are known to be highly complex, three dimensional flows with real fluid effects.
16. Rotordynamic Forces in Cavitating Inducers - Bhattacharyya, Abhijit; Acosta, Allan J.; Brennen, Christopher E.; Caughey, Thomas K. This paper reports an experimental investigation of the rotordynamic forces that occur in a whirling three bladed inducer under the influence of cavitation.
17. Rotordynamic Forces in Cavitating Inducers - Bhattacharyya, A.; Acosta, A. J.; Brennen, C. E.; Caughey, T. K. This paper reports an experimental investigation of rotordynamic forces in a whirling axial flow inducer under the influence of cavitation at various flow coefficients.
18. Aging and Degradation in Dilute Polymer Solutions - Brennen, C. E.; Gadd, G. E. This paper describes studies of the properties of dilute solutions of polymers which have been found to reduce friction in turbulent flows.
19. Wave Patterns on the Surface of Hydrodynamic Cavities - Brennen, C. In experiments on cavities behind various axisymmetric headforms, a pattern of waves or ripples with crests parallel to the separation line was observed on the cavity surface just downstream of separation.
20. Some Cavitation Eexperiments with Dilute Polymer Solutions - Brennen, Christopher The small vertical tunnel (figure 1) was employed to study and extend observation of the same phenomenon to smaller headforms and Reynolds numbers.
