  • System for measuring Reynolds in a turbulently flowing fluid
    Patent number: 3964306
    Abstract: A system for measuring momentum flux in a turbulently flowing fluid including a sensing apparatus for dynamically sensing the mainstream and the cross velocity components of the fluid, a transducer operative to provide two electrical output signals representative of the velocity components in the mainstream and in the cross direction, and signal processors to derive the Reynolds stress wave and the Reynolds stress.
