Dynamic Heating

GBlansk
I am trying to model some heat transfer through different materials as the heat source cycles up and down.
What is the best way to define the cycling heat source?

Thanks

What did you try? Something like defining a heat source term as follows should probably work:

  Qmin + (Qmax - Qmin)*cos(omega*t)

The heating profile is basically ramping upwards at 10 degrees per second and holding at the high temp for 5 seconds, then ramping downward at 7 degrees per second and holding at the low temp for 30 seconds, then repeating.

Then you probably can construct it using logical switch functions

I will give that a try. Thank you.

I am very new to this. My goal is to compare heat transfer between two systems:

heat source
thin layer of ceramic
polypropylene
water

vs

heat source
thin layer of ceramic
aluminum
water

as the heat source cycles.  Do you have any recommendations of samples or tutorials that I could start from?

Thanks
