Theory of radial flow of heat
WebbThe radial heat flux at any radius, q r [W.m -1 ], in the cylinder may, of course, be determined by using the temperature distribution and with Fourier’s law. Note that, with heat generation, the heat flux is no longer independent of r. The following figure shows the temperature distribution in the fuel pellet at various power levels. ______ WebbThe Flow of HeatOverviewIn 1791, the Swiss physicist Pierre Prévost (1751-1839) published a theory of heat exchanges, which described how heat is transferred from one …
