Turbulence Measurements using Double-Chip Silicon Sensors

A small directional sensitive double-chip silicon based sensor has been designed and fabricated using microelectronic technology. To determine the performance of this sensor the Reynolds stresses in a two-dimensional flat plate boundary layer were determined at a Reynolds number of ___. Comparisons with conventional hot-wire sensors were made and showed that the double-chip sensor was able to determine the turbulent stresses with the same accuracy as a cross-hot-wire
