Happy coding, and stay cool (or warm, depending on your conduction problem).

Problem: Determine the time it takes for a metal sphere to cool down in a convective environment.

A straight line from 100°C to 20°C. (Try changing k – it doesn’t matter in 1D without generation!) % Lesson 4: Radiation Exchange Between Two Black

Radiation is the emission of electromagnetic energy by all matter at a non-zero temperature. It follows the Stefan-Boltzmann Law for a gray body:

h = 100; % Convection coefficient (W/m^2.K) A = 0.2; % Surface area (m^2) Ts = 80; % Surface temperature (C) Tf = 20; % Fluid temperature (C) % Heat transfer rate Q = h * A * (Ts - Tf); disp(['Heat transfer rate: ', num2str(Q), ' W']); Use code with caution.
