create overlapping geometry
Hai,Im simulating shell and tube heat exchanger with ansys fluent 14.0. i wanted to use heat exchanger option under model but it says the zones are not overlapping.:confused: can anyone please help me with this. how to create overlapping zone between hot and cold fluid? please help me, the submission date is this friday.:( pleassseeee...thank you

Dear All,
I would appreciate if anyone could help me. Thank you. |
Check the help file of fluent its there

ya..i have go through it..it says..
If the mesh file does not already contain overlapping heat exchanger cores for primary and auxiliary fluids, then you must create a duplicate of the zone that represents the core using the following text command: mesh → modify-zones → copy-move-cell-zone and when i try it at fluent... >mesh → modify-zones → copy-move-cell-zone modify-zones/: Enter the modify zones menu. ?: Enable help mode. Type "q" to return to command mode invalid command [copy-move-cell-zone] /mesh> 3 invalid command [3] > ....................... 3 is the ID of the zone i dont know how should i respond it... i keep on trying..but my command being invalid... how should i respond back?? |
/mesh/modify-zones> slit-face-zone
Face zone id/name [] wall-4 |

thank you..but due to time limitation..i just drop on using heat exchanger model. i used interface couple method.. it was succeed... but im not sure what i did is correct...
coupled solver time step time-5s number of time step-28 the length of the shell is 70cm & velocity 0.5cm/s the length of tube-580cm - velocity 5cm/s i just did small calculation as the fluid in shell need atleast 140s to out of it & the fluid in tube needed 116s to out...thats how i come up with the time step time and the no. of it... 5s*28=140s... is it correct...?? |
