Application of Fourier’s Law in One-Dimensional Steady Heat Conduction Calculation of Cylinder Wall

When a temperature gradient exists in a body, experience has shown energy transfers from the high-temperature region to the low-temperature region. The energy is transferred by conduction. The fundamental law of heat conduction is called Fourier’s law. The problem is simple if a system is in a steady state (i.e., the temperature does not change with time). The one-dimensional heat conduction in a steady state is the simplest. Through an example, we apply Fourier’s law to analyze the one-dimensional stable heat conduction of the cylindrical wall.
