Gas ejector experiment

Gas ejector experiment

Gas ejector experiment

(OP)
Hello

Im currently working on a CFD project looking a gas ejector design, however I need a comparison of the results found from the CFD software. For this Ive managed to get hold of a small gas ejector and Im now trying to design a suitable experiment to let me measure the mass flow or pressure at the entrainment section and the exit. My first thoughts was to connect the entrainment section up to a small manometer and calculate the difference in pressure. However my tutor tells me that this would not provide accurate results as its a "dead pressure"?

Im really scratching my head now of how to go about this and would really appreciate any ideas or thoughts on this subject that anyone may have

Kind regards

RE: Gas ejector experiment

Your tutor is correct.  An ejector is a dynamic device; when any of the flows stops, it ceases to be an ejector.

You might try running it on water; it's much easier to measure the mass flows that way.


Please let us know how it went when you come back as a graduate.  Student postings are not allowed here.
