| Abstract: | The paper describes some applications of a wall shear stress sensor technique which is based on hot-wire anemometry. The
“surface hot wire” is a flush-mounted thermal resistive wire with a tiny slot underneath. The arrangement of this sensor guarantees
an improved signal-to-noise ratio compared to a common surface hot film. The setup and the application of single sensors and
of surface hot-wire arrays are shown. Some results are presented that were acquired in several experiments in the field of
laminar-turbulent transition.
