Hi,
Thanks for your help.
I need to model an duble stade ejector that uses steam as a motor fluid and sucks air without moving parts.
The ejector works continuously and no, it is not necessary to simulate the vacuum chamber.
My aim is to understand what happens if the flow rate of the incoming steam varies and the conditions of the outgoing steam.
Process data are:
I have no other information, I contacted the supplier but I am waiting.
Thanks,
Valeria
Valeria,
I have not come across a steam ejector model but the device does not seem to be all that complex. I suspect that a model could be written. Could you give me a bit more information about what you are trying to model? For instance, do you also need to model the vacuum chamber? Do you just care about the conditions of the steam that would come out of the ejector? Is the vacuum pumped continuously by the ejector or is the ejector only used periodically?
kind regards,
David
