Flow impedance
WebImpedance is the reciprocal of mobility. If the potential and flow quantities are measured at the same point then impedance is referred as driving point impedance; otherwise, transfer impedance. Resistance - the real part of an impedance. Reactance - the imaginary part of an impedance. WebElectrical impedance. In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit. [1] …

WebThis paper describes the present approach and discusses the time-domain numerical simulations of the NASA Langley flow-impedance tube with a constant depth ceramic tubular liner. Both single and broadband-frequency simulations are performed. Excellent agreement is shown with experimental data at various frequencies and flow conditions.", WebFlow resistors in a fluidic circuit are the analogous elements to electrical resistors in an electrical circuit. In these analogous circuits, the pressure [mbar] corresponds to the voltage [V], the flow rate [µL/min] to the electrical current [A] and the flow resistance [mbar·min/µL] (or hydrodynamic resistance) to the electrical resistance ...
