Size change components bring about a sudden change in velocity at the component. This can be caused by a change in the size of inlet and outlet pipes or by a sudden constriction.
In FluidFlow, the thin sharp-edged orifice, thick orifice, Inline Nozzle, and Venturi Tube components can be automatically sized. Users can choose two sizing models, Size for Flow and Size for Pressure Loss.
The table below shows the application of different size change components available in the FluidFlow database:
The table below shows the required data input and the output for the size change components. Note that the results table varies depending upon the fluid phase state and the visible properties selected by the user.
