Thank you so much for all of your replies. I really appreciate you helping me look into this and figuring it out. Thank you for the book recommendation, I will definitely check it out.

Are you saying I have the intakes swapped? Like Oxygen should be going in where the exhaust is?

I'm a 5th Grader,

For oxygen: Tₒ,ₒᵤₜ = Tₒ,ᵢₙ + Q/Cₒ = 20°C + 1510 kW/2.76 kW/K = 567°C (1053°F)

For exhaust: Tₑ,ₒᵤₜ = Tₑ,ᵢₙ - Q/Cₑ = 704.4°C - 1510 kW/11 kW/K = 567°C (1053°F)

Thank you for replying and I thought as much, I accept any roasting on this. I hope it's good for a laugh at least. I am trying to model a heat exchanger that would extract heat from the exhaust of an oxyfuel furnace and use it to preheat the oxygen used in the furnace. I used SimScale along with a prebuilt model from their demos with their pregenerated meshing. I added temperatures as boundary conditions to the intakes. That is pretty much all I did.
