APPARATUS FOR ESTABLISHING FLOW OF FLUID MASS HAVING A KNOWN VELOCITY |
摘要 |
An apparatus for establishing a flow of fluid mass, such as a gas, having a known velocity, characterized by an hermetically sealed chamber conforming to a closed-loop configuration and including a throat and a plurality of axially displaceable pistons for sweeping through the throat a stream of gas including a core and an unsheared boundary layer. Within the throat there is provided a cylindrical coring body concentrically related to the throat for receiving the core, and a chamber surrounding the cylindrical body for drawing off the boundary layer, whereby the velocity of the core is liberated from the effects of the velocity of the boundary layer.
