ANSYS Fluent Tutorial: Natural Convection Heat Transfer 2D Transient Analysis on a Solid Cylinder

Рет қаралды 66,269

Description:
In the Current tutorial, natural convection heat transfer has been modeled, for a solid aluminum cylinder. The cylinder has been kept in a rectangular chamber. The cylinder wall temperature is 500 K, whereas the surrounding air temperature is 300K, this temperature difference causes a natural convection Heat transfer between the cylinder surface and the surrounding air. This Heat Transfer has been analyzed for an unsteady(transient) case for a time period of 60 seconds. The detail variation of temperature along with time has been captured as solution animation.
What will you learn from this tutorial?
- Creating the geometry for 2D analysis.
- Meshing
- Transient analysis modeling.
- Creation of the Solution animation

Far as I know I did exactly what the video did but I do not get a result it is just blue every where. The scale indicates only 500K by the way. It seems that my Ansys has a problem with a fluid body and solid created from two or more sketches. This must have something to do with the bodies and/or interfaces not cooperation properly? Please Help anyone

Have you separated the both domain? ,check once by hiding any of the body.

I don't know if you noticed, but when you applied the "via System Coupling" B.C., the message "not applicable, so skipping it." on the console appeared, so the B.C. that was actually used was "Heat Flux", which was per default set to zero. I think it is right either way because you are saying that there's no heat flux there, so it is insulated.

Yes you are right.

Why do you need to generate the solid zone? If your interest is in the fluid natural convection, the solid surface is irrelevant. Plus the animation starts with hot solid surface but cool core seems odd.

@AnsysTutor Жыл бұрын

We are observing the temperature changes in the solid, without creating the soild zone it would be hard to know about the temperature changes upto the center of the solid.

Hey, hi! Do you know why Fluent created that B.C. named cylinder_wall-shadow? You named the cylinder wall earlier, so I got confused why the software created another B.C. related to that wall. I was thinking that maybe it is because you named using the cylinder wall, but there's the wall from the fluid domain too that corresponds to the same points in space... maybe it is that, right?

@AnsysTutor 4 жыл бұрын

Yes, generally a shadow wall is generated if there are two different cellzone, if you name the one face of a cellzone then at the other cellzone adjacent to this cellzone will create a shadow wall.
