SnorriGudmundssonBScAE, MScAE, FAA DER(ret.), inGeneral Aviation Aircraft Design, 2014 Boundary Layer Transition A body moving in a fluid will generally be exposed to three distinct types of fluid flow; one is characterized by the presence of alaminar boundary layer, another by aturbulent boun...
Streaks in a boundary layer can be generated in several ways [10]. Generally, the higher the streak amplitude, the stronger this stabilisation [6]. However, a too high streak amplitude is not desirable since then streaks themselves become unstable to inviscid secondary sinuous instabilities1 [11...
In the case of aerofoil flows, the traditional definition of boundary layer parameters as used for flat plates must be adapted to be consistent with the spatially varying potential flow. In the present study, the definitions used for the displacement thickness δ⋆ and the momentum thickness θ...
The invention relates to a method (1, 1) for monitoring the operation of a boundary layer control system equipped with an aircraft profile bodyIt is configured to actively control or control at least one boundary layer parameter (() 1) or a part of the formed form () 1. The surface ...
Solution-precipitation occurs by a dissolution of crystalline material into the glassy phase loaded in compression. Thus, diffusion occurs at the grain boundary as for Coble creep, but in theglassy layerthat acts as a rapiddiffusion path. Finally, reprecipitation occurs on interfaces loaded in tensi...
The atmospheric boundary layer (ABL) is the part of the atmosphere directly influenced by the surface. Winds in the ABL are an essential parameter in various applications such as weather forecasting, transport and aviation, and is a critical parameter in the wind energy industry. An advanced tech...
DPS (distributed propulsion system) utilizing BLI (boundary-layer ingestion) has shown great potential for reducing the power consumption of sustainable AAM (advanced air mobility), such as BWB (blended-wing body) aircraft. However, the ingesting boundary layer makes it easier for flow separation to...
the hypersonic double compression corner shock wave/boundary layer interaction by using a high-energy flow pulsed arc discharge array is verified. The control law of a high-energy flow pulsed arc discharge array acting on the double compression corner shock wave/boundary layer interaction is revealed...
[1] proposed that the flow field simulated in a wind tunnel could be similar to the actual atmospheric boundary layer (ABL) employed in wind engineering model tests, simulating the ABL has become an indispensable test procedure. To fulfill the task of simulating realistic ABL turbulent flow ...
