Adaptive wind-tunnel walls are designed to be moved to simulate “free-air” conditions and reduce or remove the aerodynamic effects of wall-interference on a model. Further, allowing the walls to be easily moved allows a standard wind tunnel design to utilise models of differing sizes from 100 per cent (such as a full-size car) down to models of 50 per cent scale or less. Often a building model can be as small as 1:300 scale. This improves the flexibility and range of testing that a wind tunnel can achieve, thus enhancing its lifespan and flexibility and breadth of application.
