This volume represents the findings of the first test cases considered by ERCOFTAC. The workshop, held in Lausanne, Switzerland, in 1990, studied five test cases: boundary layer in an S-shaped duct; periodic array of cylinders; transition in a boundary layer under the influence of free-stream turbulence; predictions of an axisymmetric jet flow in a diverging duct; and predictions of the turbulent flow in an axisymmetric geometric configuration. These cases represented the interests of both the academic and industrial groups in determining the limits of various models and codes to predict real...

Optimal Shape Design is concerned with the optimization of some performance criterion dependent (besides the constraints of the problem) on the "shape" of some region. The main topics covered are: the optimal design of a geometrical object, for instance a wing, moving in a fluid; the optimal shape of a region (a harbor), given suitable constraints on the size of the entrance to the harbor, subject to incoming waves; the optimal design of some electrical device subject to constraints on the performance. The aim is to show that Optimal Shape Design, besides its interesting industrial...
