Homework Help: Heat transfer in 2-D with different 'k' values.

    Hello. I'm a student of Univ. of Korea.

    As you can see in the attachment, I'm calculating the Temp variation in 2-D.

    The node 24 has a convection from left upper quadrant with h, a conduction from right upper with k1 and a conduction from bottoms with k2.

    I can't figure out how should I combined those different k values in one Equation...

    Thanks..

    I think you just add the power coming into 24 through each side.

    Which are the lines of constant x and which are the lines of constant y? What is the pde, including the k1 and k2? What is the mathematical expression of the convective BC?
