FUNDAMENTAL HYDRODYNAMICS RESEARCH, QUARTERLY TECHNICAL PROGRESS REPORT

Under the sponsorship of The Office of Naval Research (Code 12) AHR Program, The Applied Research Laboratory of Penn State University performs basic research in hydrodynamics and hydrodynamic noise. The hydrodynamics research conducted under this program falls into two basic areas: 1) Turbomachinery--to develop an improved understanding of the fluid mechanics and acoustics associated with low-speed turbomachines and marine propulsors and to apply this knowledge to the development of improved propulsor and turbomachine design methods; and 2) Drag Reduction--to develop a fundamental understanding of the mechanisms that cause drag on bodies and surfaces and to explore novel methods to reduce drag. This report documents the approved technical projects undertaken for the period 1 October 1989 through 31 December 1989.
