Re: Heat exchanger



Julie,

I am looking to model a heat exchanger with phase change on the cold-side (steam under vacuum). Does anybody have any advice or know of an existing model?


Apparently nobody has proposed a component to simulate your heat exchanger. Depending on the level of detail you need and what you are interested in (i.e. a complex system using the heat exchanger or the heat exchanger itself), you can either use some tricks to use existing components (e.g. Type 5 with a very high Cp for one fluid), use simple equations in your TRNSYS file, or develop a new component. If you want to develop a new component and you have the physical equations describing the heat exchanger, you could consider using Type 66 and implementing your equations in EES at first, so you can concentrate your effort on modeling and not coding. If you are satisfied with the behavior but need faster simulations, you can then rewrite the EES equations in Fortran.


I hope this helps,
