Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
This Demonstration shows heat flow through a 1m bar of selected composition, based on solutions of the 1D Fourier heat equation. Select the material and initial temperature to see the heat flow over time by moving the "time (s)" slider. As the time progresses, thermal energy initially concentrated at the center spreads out along the length of the bar.
