ABSTRACT

Application of Fourier’s law of heat conduction for the calculation of heat flow in some simple, one-dimensional systems is discussed in this chapter. The term “one-dimensional” refers to the fact that only one spacial coordinate is needed to describe the spatial variation of the dependent variables. Several physical shapes may fall in the category of one-dimensional system. For instance,

• A cylindrical or a spherical body can be treated as one-dimensional system, when the temperature in the body is a function of only the radial distance, and is independent of the azimuth angle or axial distance.
