Homework Help: 2-D temperature Distribution - Matlab or Excel

  1. Nov 7, 2011 #1
    1. The problem statement, all variables and given/known data

    I am trying to find the temperature distribution of a triangular cross section (right triangle). The left side is insulated, the other two sides are exposed to an ambient temperature and heat transfer coefficient when t>0. Both sides of the triangle are 20 cm long and we are told to make the change in x = 4 cm, and to find the temperature distribution for one hour and to use an explicit difference scheme. The triangle is intially at 20 degrees C while the outside temperature is 400 degrees C.

    2. Relevant equations

    So for explicit difference:

    Ti(n+1) = Ti(n) + Fo(Ti+1(n) -2Ti(n) + Ti-1(n))

    3. The attempt at a solution

    I have been using excel at first. I am confused at how to set up the equations for interior nodes, the corners and exterior nodes.

    I just need a good kick start . I was told by my teacher to use [A][T]=[c]
