Design and Analyze Orifice Geometry for a Fuel Metering Valve
It is noted that the parameters of a fuel metering valve are usually nonlinear, while classical linear analysis methods can be only used to analyze and optimize linear hydraulic control systems, which prevents the usage of linear analysis methods to study the effect of various parameters. In this paper, the flow rate of fuel metering valve is linearized using a flow gain(G), which optimized linkage to reconcile the linearized approach with the implementation of the nonlinear physical design. In particular, the relationship of steady-state flow gain and a shape of the flow orifice, including triangular, rectangular, and circular, are discussed. The result shows that triangular and circular shapes provide an excellent flow orifice compared to rectangular shape in the same of size and operation conditions.
