Microscopic calculation of the heat transfer between a granular structure and liquid3He

  • D. Burton

A recent formula for the heat transfer coefficient κbetween3He quasiparticles and phonons of a sintered metallic powder is evaluated using the phonon density of states of a microscopic model of a granular structure. The microscopic model describes a simple crystalline granular structure and contains extended modes only. When the dominant phonon wavelength λ is less than a typical grain size, κ possesses a low-temperature enhancement typical of a sintered metallic powder and over a limited range exhibits a linear variation with temperature.
