Wind tunnel simulation of the flow around two-dimensional hills

Ferreira, A.D. / Silva, M.C.G. / Viegas, D.X. / Lopes, A.G.

AbstractAn experimental investigation of flow around two-dimensional hills of sinusoidal cross-section is presented for Reynolds numbers in the range 1.7 × 10⁴−2.4 × 10⁵. The flow around a single hill with four different cross-sections is described by the pressure distribution on the surface of the models and by their topological features. The interaction between two identical hills is studied for varying distances. Pressure and shear-stress distributions on each hill are given, as well as vertical velocity profiles on the tops of the hills. The main properties of the flow obtained by flow visualization are shown.
