Apparatus and Method for Assisting with Fluid Pressure Measurement
Need:
In physics and fluid mechanics, a boundary layer is the layer of fluid in the immediate vicinity of a surface of interest, where the effects of viscosity may be significant. In high-performance aerospace and aeronautics designs significant resources are devoted to controlling the behaviour of the boundary layer to minimize drag. In order to control, or even understand, boundary layer behaviour, it is therefore desirable to measure and/or calculate fluid pressures, skin friction, and other properties of airflow past a surface of interest.
Solution:
Researchers at Cal Poly, San Luis Obispo have developed an apparatus for assisting with measurement of a fluid pressure includes a cover layer having a leading cover edge and upper and lower cover surfaces. When the lower spacer surface is connected to the substrate, the substrate defines a lower cavity surface and extant fluid is present within the cavity. Variable fluid flowing toward the cavity exerts pressure on the extant fluid to generate an extant fluid pressure level which is physically transmitted through the apparatus and made available for measurement as an extant fluid pressure level.
Applications:
- Fluid Mechanics
- Aeronautics designs
- Aerospace Design
Advantages:
- Provides an accurate fluid pressure measurement
