Transonic buffet for laminar and turbulent conditions

What is it about?

Transonic buffet is a flow phenomenon usually characterised by shock waves exhibiting regular oscillations on a wing. It is detrimental as it limits the maximum flight speed of aircraft. In this study, we examine two different buffet types which are classified based on whether the flow over most of the wing is smooth or turbulent. We show that while these two types can have different shock wave patterns, the fashion in which the shock waves oscillate is similar. Thus, we show that the two types are qualitative the same. Additionally, we use two different approaches for simulating transonic buffet (LES and RANS) and show that these two give consistent results.
