A Miniature Flow Sensor Capable of Determining the Instantaneous High-Frequency Wall Shear Stress Fleometry - a so-called star probe - the measurement technique is capable of detemining the shear stress or the velocity close to the wall in magnitude and direction instantaneously at high temporal resolution. Hence, the novel probe enables significant gain in sensor capabilities compared to the conv

Construction of a Flow Test Rig with a Predefined Shape of the Boundary Layer to Investigate Sand Ab by the turbulent slipstream. The train under investigation here has a number of lattice doors (side flaps) near the ground where air is sucked in with a certain amount of volume flow. To experimentally address the situation in the desert, a test rig was designed and constructed which establishes a

Analysis of the Unsteady Loads on Train Models in Wind Tunnelsmovable flaps was used to generate harmonic fluctuations in the flow upstream of the train model. The model was mounted above a moving belt to generate a more realistic underbody flow and the loads were measured using an internal balance. The tests show that the mean drag and the lateral force respo
