Summary

The report concerns the response of a shear flow to the insertion of a small obstacle at an impermeable wall. A calculation method is described which makes use of elementary potential flow theory although the solutions obtained are not potential flows. The first inviscid approximation to the response is computed explicitly in a number of different cases and qualitative features of the solutions are found in accordance with expectation. Their relevance to a more accurate determination of the flow is discussed.
