I really wanted to get ahold of a paper by DeFrate and Hoerl. The design strategy is based on the determination of optimum parameters the. FLUENT, commercially available Computational Fluid Dynamics (CFD) software, was used to model gas ejectors. A parametric study was performed on these widely adopted 1-D analytical ejector models. The equations of the constant-pressure and constant-area models were verified. I suppose I am curious about how to determine a suitable throat diameter in these situations, for instance. 2.23 Annular multi-nozzle eductor (Schutte and Koerting Co.) 49 23. ejector designed for a Proton Exchange Membrane (PEM) fuel cell system. I realize there are some existing ejector ratios that require only a throat diameter, with all other proportions of the ejector being determined from this value, such as the Langhaar ejector. I would like to go from my design parameters, such as desired suction pressure and steam temperature and pressure to determine nozzle diameter, etc. They're more along the lines of "make sure the ejector isn't choked with steam"). I've seen one textbook on the topic of steam ejectors that is now out-of-print, and haven't been able to find any suitable online resources (generally, they're very basic and don't quantify much. I was just wondering if anyone had any advice on sources of steam ejector design principles.
