Heat transfer project
Heat transfer project
(OP)
University project: So we have been asked to design a rig which basically tests insulation properties of a material. I have been tasked with coming up with a mathematical model to predict temperatures. Unluckily, we will be taught heat transfer in the next semester and I have very minimal knowledge about the subject. I need help, or formulae, to predict the temperature.
Set up:
Heat source ::(a)Insulation Material(b):: Heat/Temperature Detector
I want to know how can I predict the temperature on (b)side of the insulation wall.

Then work your way up:

Simplistically, you can start off with
heat_transferred = area*heat_transfer_coefficient*delta_temperature for the convective part.
Transfer THROUGH your insulation is conductive heat transfer:
heat_transferred = area*thermal_conductivity*delta_temperature/insulation_thickness
Assuming you design the test fixture adequately, it'll depend mostly on area and thickness of the insulation, and the fact that conservation of energy means that the heat transferred across each interface is exactly the same, so you can set up the two simultaneous equations to solve for the temperature and amount of heat transferred, assuming that the hot side of the insulation is fixed at a known temperature, and the air is a known temperature
