Understanding and predicting the effect of roughness on the laminar-turbulent transition in hypersonic boundary-layers will help the design of hypersonic flight vehicles. For this type of vehicle, it is often necessary to be able to trip the transiti

International audience; A database approach is developed to predict laminar-turbulent transition of a boundary layer over a heated wall. This approach is based on the local linear stability theory (LLST). The database method is an expansion of the ON

The projected increase in air traffic volume has led to a renewed interest in drag reduction research to reduce aviation’s environmental impact. One solution is wall suction, which can effectively postpone the laminar-turbulent transition of a boun

The common point between the wing of a small-sized drone, the blades of a wind turbine, the blades of a turbojet engine, the retreating blade of a helicopter, or even the blades of the propeller of a stratospheric aircraft, is the following one : the
