Abstract: This paper explores utilization of reverse engineering for dimensionless analysis of the performance curve of the fan. Utilizing the function curve and data provided in the reference material, this paper identifies interactions among major parameters affecting the static pressure and flow of the fan. Following the fitting, the equation P(X) is expressed via Chebyshev polynomial. It simplifies the performance curve of the fan to match the impedance curve of the system. The corresponding diagram obtained can be used to predict the operating point of dimensionless performance curve of the fan to match the impedance curve of the system. In comparison with the conventional approach, the operating point of the research method registers an error rate of under 4.97%. This method can help save the cost of experiment or simulation, accelerate the speed of operating point search and reduce the size of the fan databank.
Keywords: Chebyshev polynomial, dimensionless, impedance curve, operating point, reverse engineering, performance curve.
