| Abstract: | The simulation and measurement of inlet swirl were carried out in ground test bed by using blade type swirl generator and five-hole probes.The validation of swirl simulating and measuring methods and the feasibility of evaluation criterion were testified.Test results show that designed blade type swirl generator can efficiently simulate typical bulk swirl,local swirl and twin swirl;the intensity of generated bulk swirl can reach to 15°.Swirl measuring method is feasible and with high resolution;swirl evaluation criterion is reasonable and can directly reflect intensity and structure of swirl. |
