How do I simulate a heat sink?

adilsyyed · June 9, 2012, 09:39

I am a student so bare with me please.

I am trying to make a heat sink in the middle of the air domain, which will dissipate heat. Actually it is a dehydrator in which the fruits are to be modeled as heat sink, as they require heat during the dehydration process.

I am using ANSYS CFX 11, I tried to find about the heat sinks in the source term, in the documentation, but I didn't get a lot.

Can someone please guide me, how can I simulate such an arrangement.

You can set the heat source terms from locations listed in /Modeling Guide /Basic Capabilities Modeling /Sources /Locators for Sources. The path I mentioned is for CFX V13.0.

Input a value to the energy source to give a specific rate, or a variable one.

In the heating coil tutorial, we give a source energy equation to define the copper heating element. So in this case can I use the same approach with the negative values of energy in source equation?

Please bare with me if it is a stupid question.

It is supposed to work. :-)

Thank You very much Sir. This took a lot of time from me and I couldn't figure out anything.

Thanks again

Have a look at the heating coil tutorial from CFX. That shows you how to model sources.
