Continuous wind tunnel compressor inlet flow measurement method

The invention relates to a continuous wind tunnel compressor inlet flow measurement method. The continuous wind tunnel compressor inlet flow measurement method is used for solving the problems that flow in a pipeline in front of a compressor is non-uniform and unstable, the total pressure and static pressure of cross sections are measured by using Pitot-static probes, the speed is obtained by a Bernoulli equation, and thus, the fluctuation of calculated volume flow of the cross sections is too large, so that measured error bands of surge points and surge borders are too wide and volume flow determined during actual operation is not accurate enough. The method provided by the invention has the advantages that the inlet flow of the compressor is measured and calculated accurately, the surge borders can be determined accurately, and whether the compressor is in surging or not is accurately judged.
