A dedicated wind-tunnel campaign covering reduced frequencies (Stp) well beyond current literature is presented. This enabled a full characterisation of the wake recovery and the discovery of a previously unreported wake mixing phenomenon. We highlight three main findings: (i) enhanced wake recovery of the surging turbine is highly sensitive to thrust; (ii) wake recovery is characterised by the ratio of motion velocity amplitude to wind speed and Stp; and (iii) a previously unreported flow phenomenon improves wake recovery when the motion frequency is slightly lower than the blade passing frequency.en2366-74512026Copernicus GmbHTechnology::620: EngineeringPreprint10.5194/wes-2026-60
