Hello;

I have three cylindrical masses with a radius of 9 mm and a height of 65 mm. Their locations are [0 0 0] [20 0 0] [10 20 0]. The cylinder at position [20 0 0] has heat production load and I know the instantaneous temperature change. There is no contact between the cylinders. Heat transfer between cylinders will be by convection, conduction and radiation will be neglected. I want to analyze the effect of the temperature of this cylinder on other cylinders. The initial temperature of all cylinders is 30 C and there is heat transfer by convection between the cylinders.

Could you help me.

Thank you for your attention

Yes, I want to define the problem according to what MATLAB is able to handle ?

Then your problem cannot be that important.

For reference, this should be possible using the FEATool toolbox, see for example the tutorial:

Hello sevgi

I understand that you are looking for a way to analyze heat transfer between cylinders through means of convection.

I would like to point out an example model that provides a way to analyze heat transfer in an iron rod via conduction and convection.

The below example deals with convection, that can be useful in your case.

I hope that these example models can help you in analyzing heat transfer as per your requirements.

Thanks,

Chaitanya
