The following information is taken from the network, for reference: From Figure 3 can determine whether the results are reasonable, numerical simulation to achieve good results. Table 1 can also be seen through with the increase of flow coefficient, export static pressure is gradually decreased, while the export rate is increased, the total pressure ventilator decreases; hydrostatic imported unchanged . It can be concluded: fan flow, the pressure is low; the flow rate of the ventilator, the pressure is high. While exports in large flow fan appeared relatively small negative, but exports of great speed. In the process, part of the flow rate into static pressure to overcome the resistance to the flow of the process. 2.2 Analysis of the radial cross flow conditions at the highest efficiency (flow coefficient of 0.222), selected through the impeller outlet center line (see Figure 1), the radial cross-section analysis of the velocity vector. As can be seen from Figure 4: Face at the speed of the airflow at the blade reaches the maximum. In the volute, with the increase of the flow channel space, air flow speed is gradually reduced, because the role of the diffuser. Volute wall near the middle of the air flow velocity greater than the speed of air flow; at the exit near the volute tongue where the minimum speed of the airflow. This is because the process airflow from the inlet spiral, the direction of gas flow is changed 90 °, due to the inertia of leaving the volute wall near the speed of the airflow is relatively large. Numerical simulation shows that are reliable.
