Performance of a nonuniform rectangular resonator coupled with fluidic diodes as an acoustic blower was investigated. Nonuniform resonator with a linear area variation was used to achieve high amplitude pressure at the small end of the resonator, where the diodes were located. Experiments were done with pairs of diodes with 1, 2, 3, 4 and 5 diode elements in series. The diode elements used had two different nozzle diameters but same length. The volume flow rate and pressure were measured for each case by bubble flow method for zero back pressure case, and tank filling method for non-zero back pressure cases. It was found that higher driving amplitudes gave higher flow rates and higher load capacity. Increasing the number of diode elements also did the same except for small diode diameter cases, where the blower offers higher load bearing capacity at higher loads and lower flow rates at lower loads. The measured maximum peak pressure was 15.9 kPa and the maximum flow rate observed was 11.07 L/min of air respectively, while operating around 940 Hz.
