Description	Journal: Iop Conference Series: Earth and Environmental Science By increasing the number of tangential tubes, the structure of the traditional vortex diode is changed to improve its performance parameters. Three kinds of vortex diodes with different number of tangential tubes are designed: double tangential tubes, three tangential tubes and four tangential tubes. Fluent is adopted for numerical simulation. With the increase of the number of tangential tubes, the forward and backward resistance coefficients decrease gradually, and the impedance ratio of the comprehensive performance parameters is related to the Reynolds number. In the case of low Reynolds number, the impedance ratios of the double tangential tubes type, the triple tangential tubes type and the four tangential tubes type have little difference. In the case of high Reynolds number, the impedance ratios of vortex diodes of the three types of structures have different degree of improvement, compared with those of the vortex diode with single-tangential tube. The impedance ratio of the four tangential tubes is the highest, which is increased by about 7 times, that of the three tangential tubes is next, which is increased by about 3 times, and that of the double tangential tubes is increased by about 1 times.
