The fuselage surface pressure fluctuations on an Airbus-A320 aircraft at cruise conditions are simulated by solving a Poisson equation. The right-hand-side source terms of the Poisson equation, including both the mean-shear term and the turbulence-tu

In the presence of surface imperfections, the extent of the laminar flow regions on natural laminar flow (NLF) aircraft components can be significantly reduced, as compared to design. The present work focuses on surface bumps, which can occur, e.g.,

An in‑flight investigation of a turbulent boundary layer at Reynolds numbers up to Re_theta = 49,000
Autor:
Dunker, Christina
The ongoing attempts to gain access to the realm of high Reynolds number turbulence have resulted in the dedicated development of major experimental facilities and novel diagnostic methodologies as well as in the probing of atmospheric surface flows.

This works presents an evolution of the FlowFit method for reconstructing incompressible flow fields (specifically velocity and pressure) based on scattered velocity and acceleration data. It can thus be used to process the data obtained from Lagrang

In the analysis of Lagrangian particle tracking data, ensemble averaging with spatial bins is used to generate flow statistics. Due to the scattered nature of the particles over independent snapshots, the possible spatial resolution is directly depen

Abstract The flow around a surface mounted cube with incoming turbulent or laminar boundary layer has been topic of many experimental and numerical investigations in the past decades. Despite its simple geometry the flow generates a set of complex vo
