Abstract: The response of a fully developed pipe flow to wall mounted roughness elements of rectangular cross section was investigated experimentally using a probe with a single hot-wire. Four heights ...

Abstract: Measurements are given for the combined effects of a change of surface roughness and a simultaneous change of pressure gradient. The latter is negative in a fully developed turbulent, two-dimensional ...

Abstract: Insufficient oxygen transfer can result in anaerobic biofilms and odor generation during biochemical oxygen demand (BOD) removal in trickling filters, and can limit ammonia oxidation in nitrifying trickling filters. Since ...

Abstract: Perchlorate

Abstract: Measurements of mean longitudinal velocities, static pressure, turbulence quantities and Reynolds shear stress were made in the region between fully-developed smooth wall and rough wall flows in ...

Abstract: The mean flow field surrounding obstacles attached to a wall under a turbulent boundary layer is analyzed. The analysis concentrates on how major features of the flow are influenced by model ...
