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.
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
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
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.
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
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. 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.
