    How can I solve non-linear heat conduction with a variable thermal conductivity?

    Hi everyone I am trying to solve non linear heat conduction where thermal conductivity is function of temperature, I am solving it by finite difference method. this is my equation ∂2t/∂x2+∂2t/∂y2 *k(t)= -q (x,y) i have solved the equation taking k(t)= a-b*t,and when i further solved the...

    Graduate Nonlinear conduction,where thermal conductivity depends on temparature

    i understood about k(i,j).if i take initial values of k as ones matrix and run the program with your given sujjestion then there will be no influence or no change in values of martix K. in my code I have considerd K(T) = a - b*T where a>>b a and b are variables. i just taught i can see the...

    Graduate Nonlinear conduction,where thermal conductivity depends on temparature

    Thanks for your reply and your sujjestion, Probably What i can undestand from your sujjestion is the linear heat conduction,but i am trying to do a non linear heat conduction where thermal conductivity (K) depends on Temparature (T).If you would have any better idea of solving this kind of...

    Graduate Nonlinear conduction,where thermal conductivity depends on temparature

    Hi everyone, i am trying to solve and program a non linear differential equation in MATLAB where thermal conductivity depends on temparature.I am trying it to solve by explicit finite difference method. the given equation is ∂2t/∂x2+∂2t/∂y2 *k(t)= -q (x,y) i have solved the equation taking...
