  • Probe shapes that measure time-averaged streamwise momentum and cross-stream turbulence intensity
    Patent number: 5241866
    Abstract: A method and apparatus for directly measuring the time-averaged streamwise momentum in a turbulent stream use a probe which has total head response which varies as the cosine-squared of the angle of incidence. The probe has a nose with a slight indentation on its front face for providing the desired response. The method of making the probe incorporates unique design features. Another probe may be positioned in a side-by-side relationship to the first probe to provide a direct measurement of the total pressure. The difference between the two pressures yields the sum of the squares of the cross-stream components of the turbulence level.

  • Probe systems for measuring static pressure and turbulence intensity in fluid streams
    Patent number: 5233865
    Abstract: A method and apparatus for measuring time-averaged static or ambient pressure and turbulence intensity in a turbulent stream involve placing a plurality of probes in the stream. Each probe responds in a different manner to characteristics of the fluid stream, preferably as a result of having varying cross sections. The responses from the probes are used to eliminate unwanted components in the measured quantities for accurate determination of selected characteristics.
