Velocity profile under Shinkansen vehicle on slab track
Nihon Kikai Gakkai ronbunshu, 2015 Major sound sources remaining for Shinkansen, after the development and use of various noise reduction techniques, are the pantographs and bogies. Although aerodynamic sound generated from the bogies is highly influenced by air flow under the vehicle ...

Drag Force Anemometer Used in Supersonic Flow [PDF]
To measure the drag on a flat cantilever beam exposed transversely to a flow field, the drag force anemometer (beam probe) uses strain gauges attached on opposite sides of the base of the beam.

Investigations of Effects of Surface Temperature and Single Roughness Elements on Boundary-Layer Transition [PDF]
, 1947 The laminar boundary layer and the position of the transition point are investigated on a heated flat plate. It was found that the Reynolds number of transition decreases as the temperature of the plate is increased.
