Abstract Based on CFX technology, the internal structure of jet pulse tee was designed in this paper. Firstly, the stable oscillation range of the jet pulse tee was obtained by Control Variates. The design range of the key structural parameters was as follows: the split distance was 20-45 mm, the potential difference was 1.1-2.1 mm and the side wall angel was 6 ?-16 ?. The four factors and three levels orthogonal was designed within the scope of the structure, four factors were split distance ratio, side wall angel, potential difference ratio and depth-to-width ratio and three levels were pulse frequency, pressure amplitude and flow amplitude. The influencing factors in decreasing order of importance and optimal design was obtained. The simulation results show that the pulse frequency of the optimal model increased 0-2.5 Hz and the pressure amplitude increased 0-20 kPa by comparing with the ordinary model. The hydraulic performance test of the common tee and the jet pulse tee was carried out. The pulse frequency of the jet pulse tee was 2.0-4.0 Hz which was smaller than the simulation results, and the pressure amplitude was 17-53 kPa which was larger than the simulation results. Compared with the common tee, the flow rate of the jet pulse tee outlet was larger under different pressure conditions, which indicates that the jet pulse tee can provide stable pulse flow.
