Abstract
The progress in experimental approaches to the artificially excited turbulent separated flow has been realized by the development of the instrumentation for flow measurement. At the same time, the knowledge obtained from computational approaches often provides a guideline to the experimental study. The present article introduces two examples, i. e., turbulent separating flow in an asymmetric plane diffuser and the flow over a backward-facing step, in which the experiments and computations have provided principal materials for planning the further studies in either approaches. When the experiment is designed for a fundamental problem, the consistency with the computational approach should always be taken into account for specifying the boundary conditions as well as dynamic conditions such asReynolds number range. The accuracy in the flow measurement should also be examined by consulting the corresponding flow computations that usually better satisfies the basic physical requirements, e. g., conservation of mass flow rate.
