摘要

This article reviews the progress in the development of adaptive wind tunnel wall technology during the last decade. As the development of adaptive wall test sections (AWTS) reached a 'proof of concept' status in the mid-1990s, the follow-up research activities mainly focused on further applications in new research wind tunnels, advanced numerical methods used to assess and minimize the residual interferences and the development of adaptive slots in solid walls. This article will present the concept of adaptive slotted test sections as a new promising alternative to the known technology of AWTS. Adaptive slots can be understood as a combination of longitudinal slots associated with ventilated test sections and adaptive walls, i.e., slots in solid walls with flexible, adjustable liners to enable controlled flow in the vicinity of the walls. Flexible liners can convert conventionally slotted test sections into superior adaptive slotted test sections that can efficiently minimize wall interferences, for 2D and 3D flows. Single adaptive slots in the walls can also minimize interferences very effectively and therefore provide a rather simple adaptation method for new wind tunnel projects.
