Final rept. 21 Aug 85-20 Aug 86,
PHYSICAL RESEARCH INC TORRANCE CA
Pagination or Media Count:
Nonsteady phenomena associated with flows around smooth and rough cylinders at high Reynolds numbers 0.3 to approx. 8 million were investigated. Boundary-layer profiles were surveyed. Mean and fluctuating surface pressures were measured in both the circumferential and the spanwise directions. The mean surface pressure data are compiled and presented in the Volume 1 report using both graphical and tabular format. Mean sectional drag and lift coefficients were calculated. The drag coefficients, the base pressures, and the boundary-layer separation angles were also compared to data existing in the literature. Keywords High Reynolds number flow Circular cylinders Surface roughness Vortex shedding.
