Rayleigh flow theory
WebRayleigh flow is the specific case of frictionless flow in a constant-area duct, with heat transfer. Rayleigh flow applies to constant-area heat exchangers and combustion … Webusually called the full-wave theory or Mie theory [186,187]. With this theory, the scattering cross section does not grow inde nitely with frequency. For a sphere of radius a, the scattering cross section becomes ˇa2 in the high-frequency limit. This physical feature of this plot is shown in Figure 34.5, and it also explains why the sky is not ...
