Greetings to all.
I am trying to simulate heat transfer between 2 parallel plates.
The source plate have heat condition and I want to get temperature profile in upper plate, where heat flow through convection between the two .
Can someone assist me with some tips?
Sure! Simulating heat transfer between two parallel plates can be done using the heat equation. The heat equation describes how the temperature of a material changes over time, given its thermal conductivity, density, specific heat capacity, and the rate at which heat is added or removed. In the case of two parallel plates, the heat equation can be simplified to:
q''(x) = k * (T_2(x) - T_1(x)) / L
where:
- q''(x) is the heat flux (heat flow per unit area per unit time) through the plate at position x
- k is the thermal conductivity of the material
- T_2(x) and T_1(x) are the temperatures of the upper and lower plates, respectively, at position x
- L is the thickness of the plate
To solve this equation, you will need to specify boundary conditions for the temperature of the two plates at the edges of the domain (i.e., at x=0 and x=L). You can then use a numerical method, such as finite difference method, to solve the heat equation and obtain the temperature profile of the upper plate.
One thing to note is that the heat transfer between the two plates will also be influenced by the convective heat transfer coefficient, which describes the rate at which heat is transferred by convection between the two plates. This coefficient can be calculated using the equation:
h = (k * A) / L
where:
- A is the surface area of the plates
- k is the thermal conductivity of the material
- L is the distance between the plates
I hope this helps! Let me know if you have any further questions.
