Your videos concerning the heat exchanger design using cfd are helping me alot in doing my research project especially the mesh and set up parts.... you explained every point well and made it easy to understand... thanks... that's why I have subscribed to ur channel
Please create more CFD tutorial videos on naca Airfoil and related to turbomachinery videos in details I'm following your channel so that who are unfamiliar to CFD they also learn. You make number of videos.
Hello. Yes, I will try my best. More videos will come up in the future. Don't forget to share my videos with all your CFD friends and tell them to subscribe too.
Sir, you are Zeus CFD please can you do a CFD heat exchanger with baffles? We would like to learn more Thanks a lot PD: a CFD multipass coming soon Thanks you Zeus CFD
At last the solutions converged guys u just need to apply the boundary conditions crtly i mean for every wall cause some walls are adiabatic some should be coupled and the tube walls should be dissipate heat u just need to give some time and apply those values and it doesnt matter if not crossed e-3 mine converged at 600..iteration when all were at e-5 and energy was at e-6or7 dont worry u can get it too
When I did the same as you did in your video but with Ansys 2022 R1 I have different results. The temperature on the right of the hot domain is much colder in my project (around 340K whereas you have around 360K there). Do you know what the problem could be?
is that right that the temperature gap between tube inlet and tube outlet is so little ? may i read this data that the heating transfer effiency about this model is near to 0
If we use 'Form Part' option inside design modeller for all our solids, then the interfaces get automatically created. If you dont use 'Form Part' option in design modeller then you may have to manually create the interfaces.
@@noraishahothman4394 There is an option named 'Shared Topology' in SpaceClaim that will make sure your mesh is conformal for interfaces between different fluid regions.
Hello. Once you complete the calculation you can go to the reports tab in Fluent. There you can select method as area weighted average. Select wall fluxes and then select surface heat transfer coefficient. Then you can select the location as any surface on which you want to find out h value.
Hello. We have already used the word 'wall' while giving named selections for our boundaries. ANSYS automatically detects and assigns wall boundary conditions to all the named selections with the word 'wall' in them. Hence we do not separately need to assign any boundary conditions for the walls.
Hello Sir, I really enjoyed your video, and I'm interested in a similar simulation, but considering hydrogen as the fluid and using nickel as the material for the tank. What do I need to modify to start the simulation?
I am glad you enjoyed the video. You will have to import materials from fluent library and then assign them correctly to respective cell zones. I hope this helps.

A great video, refreshed fluent after 6 long years..
Very helpful video, many thanks for taking the time to make it.
Thanks for the explanation! It has been very useful for me
Glad to hear that! Share with all your friends too.

nice, to the point
video, can you make a video on making geometry with shared topology
Very good and understandable, practically possible vedios
Glad you think so! These videos are specially designed for better understanding of CFD software. Keep sharing and supporting.
well explained...simply amazing video.. all the best brother...❣
Thanks a lot for your wonderful comment. I am glad I could be helpful. Keep sharing and supporting.
Many thanks!
Sir please do more videos on Ansys Fluent CFX and CFD tutorial for total begginers
Is it shell and tube or double pipe heat exchanger?
Very good 👍👌
hi.. i used different materials for hot and cold. why does the contour of cold fluid shows as if the temperature doesnt change at all?
Sir, you are Zeus CFD please can you do a CFD heat exchanger with baffles? We would like to learn more
Thanks a lot
PD: a CFD multipass coming soon
Thanks you Zeus CFD
This video is very helpful, please i would like to ask how do i relate time to get outlet values for temperature, pressure
Nice explanation. Under the MODELS option in FLUENT SOLVER, we have an option for heat exchanger. Why didn't we use that option?
Well I have never used that option before but you can try to explore it.
Hello,
Can u add the download link for the design, please?
Hello Anto. The download link is already available in the video description. You can directly download the geometry and start your analysis.
But the solutions didnt converge and u said if the values are in 10^-3 its ok but the energy crossed -3 and went to -4 and -6
At last the solutions converged guys u just need to apply the boundary conditions crtly i mean for every wall cause some walls are adiabatic some should be coupled and the tube walls should be dissipate heat u just need to give some time and apply those values and it doesnt matter if not crossed e-3 mine converged at 600..iteration when all were at e-5 and energy was at e-6or7 dont worry u can get it too
I meant to say that residual values should be 1e-3 or below that. Its good to hear that your solution converged.
Why wasn't the convection heat transfer coefficient specified for the analysis? Is there any default value?
Hello. Convection heat transfer was not used in this simulation and default value of 0 was used.
When I did the same as you did in your video but with Ansys 2022 R1 I have different results. The temperature on the right of the hot domain is much colder in my project (around 340K whereas you have around 360K there). Do you know what the problem could be?
How to know the final temperature of cold water outlet?
is that right that the temperature gap between tube inlet and tube outlet is so little ?
may i read this data that the heating transfer effiency about this model is near to 0
Hello sir... why I cannot run the solver more than 2 cores in setup, if I choose more than 2 cores processor it appear exception error
With the setup why did you not have to create interfaces?
When do you have to create interfaces?
If we use 'Form Part' option inside design modeller for all our solids, then the interfaces get automatically created. If you dont use 'Form Part' option in design modeller then you may have to manually create the interfaces.
@@cfdbabaopenfoamansyscfd2972 thank you for the video and the reply. Truly helpful.
@@SOZLax39 Most welcome and keep supporting.
@@cfdbabaopenfoamansyscfd2972 I am using Spaceclaim, is there any "Form part' option as in DM?
@@noraishahothman4394 There is an option named 'Shared Topology' in SpaceClaim that will make sure your mesh is conformal for interfaces between different fluid regions.
Mine, when l press setup and then press edit why doesn’t it have to set anything??
How we calculate the average heat transfer coefficient value at the cold pipe and in hot fluid also.
Hello. Once you complete the calculation you can go to the reports tab in Fluent. There you can select method as area weighted average. Select wall fluxes and then select surface heat transfer coefficient. Then you can select the location as any surface on which you want to find out h value.
MORE VEDIOUS ON HEAT EXCHANGER
I want to learn more about CFD and CFX
sir how can we calculate pressure drop and heat transfer coefficient in shell side in ansys. which equations will be used
How to set the coupled wall interface in the fluent 6.3.26, where can I find it?
5:45 Naming the parts
7:10 start of boundary conditions
how about setting boundary condition for walls ?
Hello. We have already used the word 'wall' while giving named selections for our boundaries. ANSYS automatically detects and assigns wall boundary conditions to all the named selections with the word 'wall' in them. Hence we do not separately need to assign any boundary conditions for the walls.
@@cfdbabaopenfoamansyscfd2972 for wall setting, are you using heatflux zero ?
@@dinanatasya1281 Yes that's right.
love u bro
Thank you for your kind compliment. It just made my day. Keep sharing and supporting.
nice
Thanks
mesh açılmıyor. error veriyor
Thanks for all😇😇😇
