Aspen calculation of heat pumps
Thread Content
Can Aspen calculate heat pumps, that is, steam jet pumps! How to calculate! ? Please give me some advice! Thank you!
It seems not to work; VMG has this model
I also want to use ASPEN to simulate injectors, but I haven’t known how to start. I would also appreciate advice from experts! ! May the forum have a better tomorrow! !
It is almost impossible to simulate the injection process using Aspen. If it must be reflected in the process, it is necessary to first calculate the flow rate of the power fluid on one’s own, and then use Flash2, with the ejecting fluid and the fluid being ejected as the inlet streams, to determine the properties of the outlet fluid. In other words, only the material balance of the jet pump can be calculated. Things related to dynamics can only be simulated using Fluent
We have simulated it before using FLUENT
Aspen is designed only for thermodynamic models; although it can calculate pipe resistance (based on Bernoulli’s equation and empirical equations), it is unable to perform fluid dynamics calculations for complex flow fields. Pump jets and similar devices rely on the transfer of fluid momentum; the design of the nozzle and its installation dimensions have a significant impact on their performance, necessitating the use of computational fluid dynamics (CFD) for design calculations.
Thank you very much. Is using Fluent and CFD sufficient? I mainly need to calculate dimensions and check whether they are correct – can this software do all that? ! By the way, as a luxury request: where can I find it? The original version is beyond my means to afford… Last edited by guaiguaiyang on 2009-3-24 06:11]
Is there anyone who is a **true fluent expert! Thank you! Tell me about the simulation process of Fluent. (Mostly fine)
