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.
‘Archaic rules’ torn up to green light new nuclear
Lack of data about windpower being cheaper than nuclear was, I felt, the question that you replied to. and as the context is energy security it would...
