The paper analyzed flow characteristics in vortex diode with double tangential\ntube by numerical simulation. Compared to traditional vortex diode with one\ntangential tube, the structure of double tangential tube can reduce the forward\nresistance and improve overall performance. The symmetrical design adopted\nin vortex diode with double tangential tube; the internal flow field in chamber\nshowed symmetrical distribution in the reverse flow, which can improve the\nflow stability and accelerate the convergence speed in simulation.
