Abstract

Machine performance, including efficiency, is analyzed in direct frequency domain by measuring the input power to the machine over a range of machine speeds (frequencies, ω). A differentiable mathematical function or model is identified that characterizes the input power vs. speed functional relationship. Successive derivatives of experimental power vs. speed data enable the calculation of coefficients of the mathematical function at a plurality of points (frequencies) in the frequency domain. Performance parameters including machine efficiency, pressure, pressure drag, flow, viscous drag, frictional drag, viscosity and work may be calculated from the coefficients of the mathematical function. One or more desired, optimum or best operating point(s) for machine speed may be defined in terms of the coefficients of the mathematical function or the derived performance parameters.
