Flow past a cylinder close to a free surface

  title={Flow past a cylinder close to a free surface},
  author={By P. REICHL and Kerry Hourigan and Mark Christopher Thompson},
Two-dimensional flow past a cylinder close to a free surface at a Reynolds number of 180 is numerically investigated. The wake behaviour for Froude numbers between 0.0 and 0.7 and for gap ratios between 0.1 and 5.0 is examined. For low Froude numbers, where the surface deformation is minimal, the simulations reveal that this problem shares many features in common with flow past a cylinder close to a no-slip wall. This suggests that the flow is largely governed by geometrical constraints in the… CONTINUE READING
