Description
The component ValveEdgeTableAx is a model of a flow resistance that behaves like an orifice.
The parameterization of the ValveEdgeTableAx is done by providing the Flow coefficient alphaD and a look-up table of the Cross-sectional area as a function of the input signal. Further information regarding the formatting of the look-up table can be found in the documentation of the component ResistorTableAx. Unlike the Resistor component, the look-up table for valveEdgeTableAx is declared for the input range from -1 to 1.
The flow rate is calculated based on Flow coefficient alphaD, Cross-sectional area, density of the fluid and pressure difference between the two edges of the valve, according to the formula given below:
By variation in input signal, the cross sectional area of the valve edge is changed which in turn changes the flow through the valve edge.
