I saw a lot of similar videos about this kind of problem, but this is really simple and well explained. Thge only thing that is not specified is how to find out from FLow Sim the energy or the heat that is involved in the exchanger. In other words wat is the power lost from the hot fluid and at the same time what is the power in inmput to the cold fluid. Obviously one should be the same to the other, but how Flow Sim can give it to us. Tank you in advance. Best
To get accurate answer you have to consider convection also together with conduction equation in equation goals. However conduction will also provide you some idea with a little bit difference from actual theoretical or practical results
CFD is confined to a closed space either it is internal analysis or external analysis. Therefore, whenever fluid is exposed to atmosphere through some opening or exit it is exposed to atmospheric pressure. That's why as a boundary condition exit end pressure is considered as atmospheric pressure. Again as per continuity equation mass flow rate at entry equals to the mass flow rate at exit. That exit mass flow rate can be obtained as surface goal and even sometimes it can be considered as a boundary condition to get other inlet parameters.
@@CFD_GUIDE Yeah! I'm a last semester Mechanical engineering student, and the professor I had for solidworks didnt go over fluid simulations. Only static and heat flux sims. I appreciate your work very much ^_^
I am working on CFD of a Spiral Plate Heat Exchanger. Could you please tell how to insert circular motion to the fluid so that it moves between 2 plates?? In this video it is shown Linear flow, could you tell how to insert circular motion of fluid in it??
Sir...in case if I want to fix the outlet temperature of one fluid how to apply it using boundary conditions in solidworks flow simulation?. Thanks in advance!
That will be one optimization case. Here to maintain a fixed outlet temp you can change lot of input variables e.g. initial boundary conditions, inlet temp of fluids, mass flow rates or even inlet fluid temperatures also. You can take lot of parameters together or separately and perform parametric study and finally you will have an idea about more influenced parameter. Then with the predominant parameter you can proceed final outlet temp optimization
@@CFD_GUIDE Thanks for your reply sir. Also I would like to know Where to define the value of pressure at inlet pipes of shell and tube in solidworks flow simulation? Should I define the inlet pressure value in fluid subdomain option?
Fluid subdomain must be defined after that while applying boundary conditions again it should be applied. Everything depends on actual application & actual working method. Boundary conditions dhould be applied as per actual working mechanism
Thanks for the video sir, Actually sir right now I am facing a problem regarding to the convection heat transfer. When I applied it as you tough there is a error popup that is"it is not possible to define the heat transfer coefficient and wall temperature at the same time when heat conduction in solid enabled".
No issues at all, but I prefer a compact single model to ease simulation effect. Later on, unwanted parts or components can be disabled for having better simulation results
This tutorial was so good I used it to create a university assignment, hopefully none of my students find it 🤞🤓
Great tutorial. Answers a question in my assignment perfectly!🤩
Great content! Thank you
je vous remercie, cette vidéo ma sauvé la note. Même si on connais pas très bien l'anglais il est facile de suivre
Can We have the link of modelling of Counter Flow Heat Exchanger?

Form an equation goal to have heat lost or heat gained.
To get accurate answer you have to consider convection also together with conduction equation in equation goals. However conduction will also provide you some idea with a little bit difference from actual theoretical or practical results
can you explain what is the different enviromental pressure and outlet mass flow? im still confused using these two. thank you

This video is extremely helpful! Thank You so much. Definitely subscribed for more.
I am happy to see your interest in CFD.

Hi sir can you please send me the link of cad file that you used above video
Thank you for your comments. Actually it is a very simple model and I have deleted this file immediately after uploading. I am so sorry.
Your videos are very helpful....

For the time being have the conception from this one. Soon I will make it. ruclips.net/video/dbDCkrR6vXw/видео.html
Hi. what about if I need to know the wall temperature on the inner pipe.
Simply add a surface goal for the walls
@@CFD_GUIDE . Hi. thank you for answering. I would like to know if I'd need to add boundary conditions for each of the pipe walls.

If you want to condider convection from outer wall to atmosphere you have to consider external analysis.
@@CFD_GUIDE thanks for the reply sir
Is that two different parts assembled together or just one part?
It is single part
@@CFD_GUIDE is it fine to make it as two parts and then assembled?
No issues at all, but I prefer a compact single model to ease simulation effect. Later on, unwanted parts or components can be disabled for having better simulation results
I made it as a single part, but assembly is also ok
@@CFD_GUIDE thank you very much. Very good channel bro👍 subscribed!
