Suction pressure[Pa] vs Suction flow[kg/s]

The HD150 Aerodin Coanda ejectors have 2 main dimensions and also 3 geometric dimensions and 2 other thermodynamic supply parameters (pressure and temperature) in order to control the flow and make the necessary adjustments or each flow conditions and each customers needs.
The Coanda ejector is more complex flow device than a simple rotor fan or blower therefore the flow characteristics is done by adjustments of geometric dimension, pressure and temperature. The input temperature is critical for the efficiency of the device therefore the efficiency is not shown on the diagram because is depending on the input local customer conditions.
We present only five representative diagrams suction pressure [relative Pa] vs suction flow [kg/s] for different "p" supply pressures [barg] as follows:






The diagrams were estimated using Coanda ejectors compressible inviscid flow theory based on AERODIN know-how and there are not fix but closer to the experiments.
