An algorithm for the digital support of the performance of small-sized aerodynamic experimental setups

The paper considers the use of computer experiments and digital twinning of small-sized wind tunnels to verify the results obtained during physical experiments using this type of tunnels and their validation in aerodynamic problems, as well as to ensure the digital support of their life cycle when conducting model experiments in such fields as structural aerodynamics. The data obtained from a full-scale experiment are used to create a digital twin in an aero-dynamic setup with a small working area, as well as to perform the computer simulation of the experiment thereon. The exact geometric similarity between the physical tunnel and its digital model allows obtaining highly consistent experi-mental results, i.e., close values of the distribution of wind flows, their directions and velocities. In turn, it is necessary for the development of an effective methodology for verifying experimental results in small-sized wind tunnels, in par-ticular, when designing buildings and structures and calculating building structures for wind loads. Based on the ob-tained results, an algorithm is proposed for the digital support of the performance of small-sized aerodynamic experi-mental setups.
