Random heat evolution problem

edited January 2021 in Assignments

(5 pts)

A metal bar with a given initial temperature distribution $g(x)$ lies along the unit interval. At time zero, it's left and right endpoints are placed against two large temperature wells. Your task is to sketch the evolution of the resulting temperature flow. Get your specific question by choosing your name from the menu on this webpage.

In your response, you should state your question, draw your solution by hand, and upload an image of the result.

    A metal bar of length 1 lies along the unit interval. Its temperature distribution is given by $$g(x)=4x^2−1x.$$ At time $t=0$, its left end is set to temperature 2 and its right end to 0. Here is my (tentative) sketch the temperature distribution at times $t=0$, $t=0.01$, $t=0.1$, and $t=10$.

    A metal bar of length 1 lies along the unit interval. Its temperature distribution is given by

    $$g(x) = 4x^2 - 2x.$$

    At time $t =0 $, its left end is set to temperature 1 and its right end to 0. Here is a sketch of the the temperature distribution $u(x,t)$ at times $t = 0$, $t = 0.01$, $t = 0.1$, and $t = 10$.
