Hi all, 

I am trying to model a syringe squirting liquid and finding it more challenging that expected (I am new to Fluent). Does anyone have any good videos/resources they can point me to? Furthermore, does anyone have any resources for biomedical models in general or know of an online comminity for biomedical CFD? I am going to be doing things like modeling a mucus layer in the future. 

I will note that I have looked in the ANSYS Learning hub, and I have tried following ANSYS's "Reed Valve and Piston" video for modelling the 'piston' part of the syringe. 

Thanks in avance.

There's an inkjet printer tutorial somewhere, that may be an older one on the ALH or in Fluent's Help system. That's a pretty close match to a syringe.  I'd also question the need to model the piston and exiting liquid unless the back pressure on the needle alters the piston speed. 

Otherwise, have a look on ansys.com as we've (Fluent and then Ansys) run a range of webinars, seminars, blogs etc over the last 20 years or so.   Here's a starting point   https://research.rug.nl/en/publications/computational-modelling-for-dry-powder-inhalers  but consider how wide a range of applications there are too.
