General Description

The Computer Controlled Flow of Compressible Fluids Unit, "HFCC", allows to study the variation of pressure and density, the speeds of the fluid, the different fluctuations that the fluid presents when fluids across different sections in a pipe, and the thermodynamics and fluid dynamics characteristics that the fluid has.

The air enters by the intake tube, where there is a dust filter. It provides a current free of particles in suspension and other substances dragged by air.

After the filter, the flow is measured with a Pitot tube installed in the pipe.

After the air is impelled by the turbine, it leaves this device through a straight pipe that includes a safety relief valve, a thermocouple that measures the outlet temperature and a static pressure manometer that measures pressure inthe wall of the tube.

There is a quick-release fitting at the outlet of the exhaust pipe to connect the different accessories of the unit.

This unit allows for studying different flow situations:

  • Abrupt widening.Venturi tube.Ball valve.Bend of 90°.Orifice plate.Straights pipes sections.Laval nozzle.

To analyze the different parameters studied, all accessories have the connections for the instrumentation included.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + aControl Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
