An Integrated Silicon Based Pressure-Shear Stress Sensor for Measurements in Turbulence Flows

By the introduction of silicon micro machining into fluid mechanics the experimentalists have been given a new incentive to carry out measurements of fundamental parameters in turbulent flows. One such unknown parameter is the pressure-velocity correlation (PVC) which turns out to be a key term in the kinetic energy budget as well as in the transport equations for the Reynolds stresses.
