The use of curved screens for generating uniform shear at low Reynolds numbers

摘要

A semi-empirical approach has been applied to compute the shape of curved wire screens that would generate uniformly sheared flows in a water channel as well as the effect of Reynolds number on the value of the generated shear. Experiments with such screens at mean Reynolds numbers (based on the wire diameter) in the range 8–74 were found to be in fair agreement with the predictions.
