Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NONUFM, volume 40)

Summary

Numerical and experimental investigations of the flow over surface-mounted obstacles in fully developed channel and pipe flow have been performed. The numerical work was restricted to two-dimensional geometries and results obtained with the k- turbulence model were compared with those obtained using a second-moment turbulence closure model. The experimental work included obstacles of finite length in the channel flow, with very detailed velocity measurements (LDA) being performed for the cube obstacle. Unique characteristics of two and three dimensional flow fields have been identified. Most recent results include the time dependent behaviour of these flow fields, studied using flow visualization and two-component velocity measurements.
