Study on the Influence of Probe Support Change on Measurement Results and Flowfield
Taking the small-sized and high-load booster stage intermediate duct flow passage as the object,the influence of total Temperature and total pressure and strut wake on the flowfield at the measuring points of waist struts with the diameters of 12 mm and 12x6 mm without probe was studied by numerical simulation.The results show that the total pressure loss at the inlet and outlet of the waist strut is smaller than that of the cylindrical strut;Changing the probe support rod greatly affects the pulsation results of the total temperature and total pressure at the measuring point.The influence of strut wake on the circumferential flowfield can reach several times the size of strut.
