Research on Pressure Drop Transfer Standard Based on CFD


Article Preview

The pressure drop transfer standard is a major measurement element in the pressure drop measurement device as a traceability element. This paper analyzed the air flow in the capillary tubes, and mathematical model of pressure drop transfer standard was got by the differential pressure at inlet non-laminar flow part and differential pressure in the laminar flow part. A CFD method adopting laminar model is used to confirm the theory. The pressure drop value was calculated by the diameters and length of all capillary tubes measured by OGP video measuring systems, and the result shows the calculated value was verified by the calibration value.
