Experiments on homogeneous air exhaust by equalizer

Presents the experiment principle and devices, compares the air velocity in branches of natural exhaust pipes and those of equalizer exhaust pipes, and compares the air exhaust distance with the equalizer regulation and conventional valve regulation. Results show that the equalizer can improve markedly the characteristics of exhaust pipes, and the homogeneous exhaust distance by equalizers is much longer than that by conventional valves. The flow rate of air outlet is commonly determined by the static pressure of cross-section in main duct and the impedance generated by the equalizers.
