#Eductor vs ejector software#
We appreciate that Customers often purchase this software to help with trouble shooting of a specific ejector If anything, slightly conservative values have been used.įeedback and suggestions will be gratefully received. efficiencies, based on normal practice and calibration versus installed ejectors. Thermodynamic and fluid dynamic equations These are based on standard assumptions for angles and ratioĪnd may not be identical to your actual installed units.Įzejector programs includes the following: Preliminary dimensions can be viewed – see below. The Ezejector results include a graph showing how the entrained gas flow rate will (see below) change depending on the entrained gas pressure, for at fixed discharge pressure.This allows you to estimate the impact of entrained gas flow rate on the suction pressure.The program inclues a feature to evaluate the impact of increased back pressure. Typical values will depend on the motive gas pressure and the entrainment ratio. Note that efficiency is low for an ejector. Where the compression ratio is high, it may be be more efficient to use more than one ejector stage.The overall ejector efficiency is calculated. Convergence percent (normally >99%) is supplied to confirm that the program has run successfully. The motive gas Mach No is provided for information. These are more indicative of the response of a specific ejector to changes in inputs. Therefore ejector curves at fixed ejector geometry are calculated at the design discharge pressure and an increased discharge pressure (see 3.2). Thus the results in the tables above for different gas flow rates, pressures or temperatures do not represent the performance of a specific ejector. If for example the entrained gas flow rate is changed, the mixing diameter will also change – which will have some impact on the discharge pressure. The program calculates the best nozzle and mixing diameters based for the input values. Mixing section diameter is a function of the preceding and entrained gas flow rate, pressure, temperature & molecular weight. Motive nozzle diameter is a function of motive gas flow rate, pressure, temperature & molecular weight. The nozzle and mixing section diameter are calculated. The key results and supplementary results are shown below. In the updated revision of the software, flow rate input units should be selected as either kg/hr or Nm3/hr. The inputs required are shown in the table below. Please understand that this program is for your use only and prevent access by any outside party.
